Krishnan, R. S. published an article in 1945, the title of the article was Raman spectra of the second order in crystals. I. Calcite.Recommanded Product: 452-75-5 And the article contains the following content:

cf. C.A. 40, 5142.9. The importance of the second-order Raman spectra of crystals in providing information regarding the dynamical and optical properties of crystals is emphasized. The first- and second-order Raman spectra of calcite are photographed with Hg resonance radiation (λ 2536.5 A.). The frequency shifts and widths of the five lines of the first-order spectrum are accurately measured. The second-order spectrum is composed of 11 lines of varying intensity and width, some of which appear also in the infrared spectrum with very nearly the same ν. The frequencies have been assigned as some of the octaves and allowed combinations of the fundamental νν of the calcite lattice. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Recommanded Product: 452-75-5

4-Chloro-2-fluorotoluene(cas:452-75-5) belongs to chlorides. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.

Hein, D. W.; Pierce, Elliot S. published an article in 1955, the title of the article was New pigments from 3,3′-dichloro- and 3,3′-dimethoxy-4,4′-diaminostilbene.Computed Properties of 38939-88-7 And the article contains the following content:

Two new pigment intermediates, [4,3-H2N(CL)C6H3CH:]2 (I) and [4,3-H2N(MeO)C6H3CH:]2 (II), and from them, by diazotizing and coupling with variously substituted acetoacetanilides, 1-phenyl-3-methyl-5-pyrazolone (III), and 3-hydroxy-2-naphthoic acid arylides, a number of new pigments have been prepared The new pigments show bathochromic color shifts as expected when compared with the corresponding pigments from [4,3-H2NCl)C6H3]2 (IV). The differences in the visual light absorption curves are rationalized. 2,5,4-H2N(Cl)(O2N)C6H2Me deaminated by a standard method yielded 65% 3,4-Cl(O2N)C6H3Me (V), yellow oil, b3 108°, m. 22.5°, nD26 1.5617, nD68.5 1.5426. A slow stream of O passed with high speed stirring into 5 cc. Me2CO in 200 cc. 33% KOH in MeOH containing 5 g. V during 2 hrs. with cooling and then 3 hrs. without cooling, the mixture poured into 2 l. H2O and filtered, and the filter residue washed with H2O and EtOH, dried (4.2 g.), and recrystallized from 250 cc. glacial AcOH gave [3,4-Cl(O2N)C6H3CH:]2 (VI), uniform yellow needles, m. 284-5°. In a similar run carried out at room temperature only a red solid was produced; a similar run drowned after 1 hr. stirring at 3° contained considerable [3,4-Cl(O2N)C6H3CH2]2 (VII). V (5.0 g.) stirred with 100 cc. 33% KOH in MeOH at 0° the mixture warmed slowly, the red color discharged with 30% H2O2, the solution warmed on the steam bath, treated portion wise with H2O2 until no further color was formed, diluted with 5 volumes H2O and filtered, and the filter residue washed with H2O and Et2O, dried (1.0 g.), and recrystallized from 100 cc. glacial AcOH gave VI, long yellow needles, m. 285-6°; in runs with 3, 10, and 30% H2O2 the yields varied from 0 to 56% and the product always contained some VII. Several low melting batches of VI boiled with EtOAc and filtered, and the filtrate cooled gave VII, crystals, mainly rhombs, m. 178-80°, contaminated with traces of needles. VI (31.5 g.), 126 g. 70-2% NaSH, and 1600 cc. 95% EtOH refluxed 4 hrs. with stirring and poured into 6 l. H2O, the solid precipitate filtered, washed with H2O, dried (16.8 g.), and recrystallized from 1300 cc. absolute EtOH gave 7.5 g. I, very light tan leaflets, m. 200-1°. I in EtOH saturated with HCl gave I.2HCl, needles, m. 276-7°. I.2HCl (5.28 g.), 12 cc. 5N HCl, and 45 cc. H20 diazotized at 5° with 30 cc. N NaNO2, the solution stirred 20 min., treated with H2NSO3H, and filtered cold with Super-cel, the filtrate buffered with 13.5 cc. 2N NaOAc and added dropwise with stirring to 3.9 g. AcCH2CONHPh (VIII) slurried in slightly acidic medium (by precipitation of a solution in 6 cc. 5N NaOH and 40 cc. H2O with glacial AcOH), the mixture stirred 2 hrs. without cooling and 1 hr. at 85-90°, and filtered hot, and the solid washed with H2O and dried gave 4.7 g. orange-yellow pigment with a red-brown mass tone and orange yellow tint tone. Similarly were prepared pigments with I from the following coupling components (coupling component, % yield, mass tone, and tint tone given): III, 98, bright red, yellow-red; o-AcCH2CONHC6H4Me (IX), 94, red-brown, orange-yellow; 1-C10H7NHCOCH2Ac, 84, red-brown, orange-yellow; o-AcCH2CONHC6H4OMe (X), 76, red-brown, orange-yellow; acetoacetcresidide, 122, orange-brown, orange; acetoacetpseudocumidide, 89, yellow-brown, orange-yellow; 2,4-acetoacetoxylide, 93, red-brown, orange-yellow; benzoylacetanilide, 85, orange-brown, orange-yellow; p-O2NC6H4NHCOCH2Ac, 89, dull red, light dull red; o-ClC6H4NHCOCH2Ac, 105, red-brown, orange-yellow; 3-hydroxy-2-naphthanilide, 127, blue-black, blue-gray; 3-hydroxy-2-naphtho-o-phenetidide (XI), 92, red-black, lavender; yields in excess of 100% were due to the presence of excess coupling component, precipitated by the acid coupling conditions, and not washed out by the hot H2O; the excess coupler was extracted with hot EtOH; the mass tones and tint tones are those of the crude pigment; the yields of the pigments were essentially quant. after hot EtOH extraction 3,4-MeO(O2N)C6H3Me (XII) (2 g.) added at 10° to 100 cc. 33% KOH in MeOH, the mixture bubbled 2 hrs. with rapid stirring with O, diluted with 500 cc.

XII (8 g.) stirred 6 hrs. in a similar run gave 5.7 g. XIII, m. 194-6°; if O was introduced at the same time as the Me2CO solution of XII a higher melting product, m. 190-240°, was obtained which was not further characterized. XIII (5 g.) and 15 g. Na2S.H2O in 200 cc. EtOH refluxed 4 hrs., cooled, poured onto ice, and filtered, and the filter residue washed and dried gave 4 g. II, light yellow-tan flakes, m. 148-50°. II (1.35 g.) in 100 cc. H2O and 10 cc. N HCl heated with stirring until dissolved, the solution cooled to 10°, treated with 11 cc. N NaNO2, stirred 1 hr., and treated with a small amount H2NSO3H, and the bisdiazonium solution coupled in the usual manner with III gave a red-black pigment, 94%, with a dull red-brown tint tone. XI gave similarly 116% blue-black pigment with a red-blue tint tone. A fairly rapid stream of O passed into 200 cc. 33% KOH in MeOH with high speed stirring, the mixture treated with stirring and O addition during 20 min. with 5 g. 2,4-Cl(O2N)C6H3Me in 30 cc. warm absolute EtOH, the purple color discharged, the mixture poured into 3 l. H2O and filtered, the solid washed with H2O and 95% EtOH, and dried, and the yellow crystalline solid (4.5 g.) recrystallized from 25 cc. PhNO2 gave 2.2 g. [2,4-Cl(O2N)C6H3CH:] (XIV), long yellow needles, m. 294-6°. XIV (57 g.) and 220 g. 70-2% NaSH in 2850 cc. 95% EtOH refluxed 3 hrs. with stirring and drowned in 10 l. H2O gave in the usual manner 37.0 g. [2,4-Cl(H2N)C6H3CH:]2 (XV), yellow needles, m. 180-5°; XV.2HCl, decomposed at 286°. XV.2HCl (1.76 g.) slurried with 100 cc. H2O and 4 cc. 5N HCl, cooled to 0°, treated with 10 cc. N aqueous NaNO2, stirred 15 min., treated with H2NSO3H, and filtered cold with Supercel and the solution coupled with various coupling components gave pigments (coupler, % yield, mass tone, and tint tone of pigment given): III, 93, bright-red, orange; VIII, 88, orange-brown, orange-yellow; XII, 94, orange-brown, orange-yellow; XIII, 86, red-brown, orange-yellow; XI, 113, red-black, violet. (p-H2NC6H4CH:)2 (1.05 g.) in hot 6 cc. 5N HCl and 50 cc. H2O cooled to 5° and diazotized in the usual manner, and the solution coupled with III gave 97% pigment with a bright-red mass tone and a yellow-red tint tone. Similar coupling with XII gave a yellow brown pigment, 91%, with a yellow-orange tint tone.

cf. C.A. 50, 9533b. The topmost portion of the 3rd internode in etiolated 7-day-old pea stems contained a definitely outlined region where Janus Green B (I) was reduced to diethylsafranin. Some cells in this region, particularly those adjacent to the starch sheath, formed stable, copious, brilliant blue-green precipitates of A-type vacuoles. Combined staining with I and neutral red separated red precipitates from blue mitochondria. The latter were recognized by the reversible coloration and decolorization of I under aerobic and anaerobic conditions, resp. They became dark red when incubated with neotetrazolium chloride.

On November 15, 2018, Wohlfahrt, Patrick; Troost, Esther G C; Hofmann, Christian; Richter, Christian; Jakobi, Annika published an article.Recommanded Product: 99-60-5 The title of the article was Clinical Feasibility of Single-Source Dual-spiral 4D Dual-Energy CT for Proton Treatment Planning Within the Thoracic Region.. And the article contained the following:

PURPOSE: Single-source dual-spiral dual-energy computed tomography (DECT) provides additional patient information but is prone to motion between the 2 consecutively acquired computed tomography (CT) scans. Here, the clinical applicability of dual-spiral time-resolved DECT (4D-DECT) for proton treatment planning within the thoracic region was evaluated. METHODS AND MATERIALS: Dual-spiral 4D-DECT scans of 3 patients with lung cancer were acquired. For time-averaged datasets and 4 breathing phases, the geometric conformity of 80 kVp and 140 kVp 4D-DECT scans before image post-processing was assessed by normalized cross correlation (NCC). Additionally, the conformity of the corresponding DECT-derived 58 keV and 79 keV pseudo-monoenergetic CT datasets after image post-processing, including deformable image registration (DIR), was determined. To analyze the reliability of proton dose calculation, clinical (PlanClin) and artificial worst-case (PlanWorstCase, targeting the diaphragm) treatment plans were calculated on 140 kVp and 79 keV datasets and compared with gamma analyses (0.1% dose-difference and 1 mm distance-to-agreement criterion). The applicability of a patient-specific DECT-based prediction of stopping-power ratio (SPR) was investigated and proton range shifts compared with the clinical heuristic CT-number-to-SPR conversion were assessed. Finally, the delineation variability of an experienced radiation oncologist was quantified. RESULTS: Dual-spiral 4D-DECT scans without DIR showed a high geometric conformity, with an average NCC ± standard deviation of 98.7% ± 1.0% when including all patient voxels or 88.2% ± 7.8% when considering only lung. DIR improved the conformity, leading to an average NCC of 99.9% ± 0.1% and 99.6% ± 0.5%, respectively. PlanClin dose distributions on 140 kVp and 79 keV datasets were similar, with an average gamma passing rate of 99.9% (99.2%-100%). The worst-case evaluation still revealed high passing rates (99.3% on average, 92.4% as minimum). Clinically relevant mean range shifts of 2.2% ± 1.2% were determined between patient-specific DECT-based SPR prediction and clinical heuristic CT-number-to-SPR conversion. The intra-observer delineation variability was slightly reduced using additional DECT-derived datasets. CONCLUSIONS: The 79 keV pseudo-monoenergetic CT datasets can be consistently obtained from dual-spiral 4D-DECT and are applicable for dose calculation. Patient-specific DECT-based SPR prediction performed well and potentially reduces range uncertainty in proton therapy of patients with lung cancer.

Axon, David R; Chinthammit, Chanadda; Tate, Jared; Taylor, Ann M; Leal, Sandra; Pickering, Matthew; Black, Heather; Warholak, Terri; Campbell, Patrick J published an article in 2020, the title of the article was Current Procedural Terminology Codes for Medication Therapy Management in Administrative Data..Application of 99-60-5 And the article contains the following content:

BACKGROUND: Three pharmacist-specific Current Procedural Terminology (CPT) codes exist to facilitate medication therapy management (MTM) reimbursement (codes 99605, 99606, and 99607). However, no studies have used CPT codes in administrative claims databases to identify subjects who have received MTM services. OBJECTIVE: To assess the prevalence of MTM services provided, using CPT codes identified in an administrative dataset. METHODS: A retrospective cohort study was conducted using a subset of Medicare Part D individuals from the IBM MarketScan Medicare Supplemental Research Databases (2009-2015). Researchers identified beneficiaries who received MTM services using CPT codes 99605, 99606, and 99607. RESULTS: Of the 16,483,709 individuals in the dataset, only 3,291 had CPT codes indicating that they received MTM services, representing an overall prevalence of 0.020%. CONCLUSIONS: The use of CPT codes as an indicator of MTM service provision resulted in far lower MTM utilization rates than in published literature. Reliance on CPT codes to identify MTM services in administrative claims is not recommended, given that it limited the researchers’ ability to properly identify patient receipt of such services. More accurate methodologies are warranted for identifying MTM use and its effects on patient outcomes.

And the article contained the following:

Background: A high consumption of fruit and vegetables is possibly associated with a decreased risk of colorectal cancer (CRC). However, the findings to date are inconsistent. Objective: We examined the relation between self-reported usual consumption of fruit and vegetables and the incidence of CRC. Design: In the European Prospective Investigation into Cancer and Nutrition (EPIC), 452,755 subjects (131,985 men and 320,770 women) completed a dietary questionnaire in 1992-2000 and were followed up for cancer incidence and mortality until 2006. A multivariate Cox proportional hazard model was used to estimate adjusted hazard ratios (HRs) and 95% CIs. Results: After an average follow-up of 8.8 y, 2,819 incident CRC cases were reported. Consumption of fruit and vegetables was inversely associated with CRC in a comparison of the highest with the lowest EPIC-wide quintile of consumption (HR: 0.86; 95% CI: 0.75, 1.00; P for trend = 0.04), particularly with colon cancer risk (HR: 0.76; 95% CI: 0.63, 0.91; P for trend < 0.01). Only after exclusion of the first 2 y of follow-up were these findings corroborated by calibrated continuous analyses for a 100-g increase in consumption: HRs of 0.95 (95% CI: 0.91, 1.00; P = 0.04) and 0.94 (95% CI: 0.89, 0.99; P = 0.02), resp. The association between fruit and vegetable consumption and CRC risk was inverse in never and former smokers, but pos. in current smokers. This modifying effect was found for fruit and vegetables combined and for vegetables alone (P for interaction < 0.01 for both). Conclusions: These findings suggest that a high consumption of fruit and vegetables is associated with a reduced risk of CRC, especially of colon cancer. This effect may depend on smoking status.
