The article was 《Density, viscosity, and saturated vapour pressure of 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene》. The article mentions the following:

D. and viscosity data of pure 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene were obtained in temperature range from 318.15 K to 348.15 K at the local atm. pressure of 99.7 kPa. The value of corresponding saturated vapor pressure of two isomers were determined in the temperature range of 409 K to 517 K. The relationship between temperature and d. can be well correlated by the linear equation. The viscosity data was well described by the Litovitz, Ghatee, VFT, and Andrade equations, and the calculated value by the VFT equation is consistent with the measured data. Both the Antoine and Riedel equations can accurately describe the relationship between saturated vapor pressure and temperature of 3-chloro-4-fluoronitrobenzene and 3-chloro-2-fluoronitrobenzene, which can meet the requirements for chem. design. In addition, the thermal expansion coefficient was determined based on the d. data, and the molar vaporisation enthalpy of two isomers was evaluated using the Clausius-Clapeyron equation. In the experimental materials used by the author, we found 3-Chloro-4-fluoronitrobenzene(cas: 350-30-1Related Products of 350-30-1)

3-Chloro-4-fluoronitrobenzene(cas: 350-30-1) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.Related Products of 350-30-1

The article was 《Discovery of (R)-9-Ethyl-1,3,4,10b-tetrahydro-7-trifluoromethylpyrazino[2,1-a]isoindol- 6(2H)-one, a Selective, Orally Active Agonist of the 5-HT2C Receptor》. The article mentions the following:

Robust pharmaceutical treatment of obesity has been limited by the undesirable side-effect profile of currently marketed therapies. The synthesis and optimization of a class of pyrazinoisoindolone-containing, selective 5-HT2C agonists as antiobesity agents, are described. Key to optimization of the pyrazinoisoindolone core was the identification of the appropriate substitution pattern and functional groups which led to the discovery of compound I, a 5-HT2C agonist with >300-fold functional selectivity over 5-HT2B and >70-fold functional selectivity over 5-HT2A. Oral dosing of I reduced food intake in an acute rat feeding model, which could be completely reversed by a selective 5-HT2C antagonist and caused a reduction in body weight gain in a 4-day rat model.

Emami, Leila; Khabnadideh, Soghra; Faghih, Zahra; Solhjoo, Aida; Malek, Saba; Mohammadian, Amir; Divar, Masoumeh; Faghih, Zeinab published an article in Journal of Heterocyclic Chemistry. The title of the article was 《Novel N-substituted isatin-ampyrone Schiff bases as a new class of antiproliferative agents: Design, synthesis, molecular modeling and in vitro cytotoxic activity》.Synthetic Route of C7H6Cl2 The author mentioned the following in the article:

Thirteen novel isatin-ampyrone Schiff bases derivatives such as I [X = H, Cl; R = H, 3-F, 4-OMe, etc.] were synthesized by the reaction of isatins and benzyl halides followed by condensation with ampyrone. In vitro cytotoxic activity of these new Schiff bases against three human tumor cell lines (MCF-7, A549, and SCOV3) as well as normal breast cell line (MCF-10A) were evaluated by MTT assay. Structure-activity relationship of the tested compounds revealed that chlorine group at C-5 position of the isatin ring significantly increased the cytotoxic activity. This study generally led to introduce a highly active mol. I [X = Cl; R = 3-Cl] with IC50 values of 5.12, 25.5, and 12.9μM, on MCF-7, A549, and SCOV3, resp. Furthermore, mol. docking studies of the synthesized compounds were also done to investigate their binding modes to toward VEGFR-2 and JNK3-MAP kinase as the main targets for isatin-containing anticancer agents. Binding free energy values of the compounds showed pos. correlation with their cytotoxic activities. To confirm the docking results, mol. docking simulations of potent compound I [X = Cl; R = 3-Cl] against VEGFR-2 and JNK3 MAP kinase were also performed. According to the cytotoxic results and in silico ADMET predictions together, I [X = Cl; R = 3-Cl] could be considered as a potent candidate for the future anticancer studies.

Magid, L. J.; Han, Z.; Li, Z.; Butler, P. D. published an article in Journal of Physical Chemistry B. The title of the article was 《Tuning the Contour Lengths and Persistence Lengths of Cationic Micelles: The Role of Electrostatics and Specific Ion Binding》.Formula: C7H3Cl2NaO2 The author mentioned the following in the article:

Small-angle scattering was used to obtain detailed information on micellar contour lengths and persistence lengths, a measure of micellar flexibility, for mixed micelles of cetyltrimethylammonium 2,6-dichlorobenzoate and cetyltrimethylammonium chloride in H2O as a function of surfactant and salt concentrations and the relative amounts of the 2 counterions (the counterion inventory) at the micellar surface. Increasing amounts at the surface of the penetrating counterion of the pair, 2,6-dichlorobenzoate, lowers the 1-dimensional bending modulus of the micelles, making them more flexible. Micellar contour lengths exhibit a maximum with increasing amounts of 2,6-dichlorobenzoate at the micellar surface. This is understood in terms of decreases in the micellar end-cap energies, Ec, at high concentrations of penetrating counterion. By decreasing the effective micellar surface charge d., penetrating counterions also cause decreased contributions from electrostatic repulsion, Ee, which retard micellar growth. At low ionic strengths, this results in more extensive micellar growth upon addition of Na 2,6-dichlorobenzoate rather than NaCl. In the experiment, the researchers used Sodium 2,6-dichlorobenzoate(cas: 10007-84-8Formula: C7H3Cl2NaO2)

In 2019,Food Research International included an article by Rios-Mera, Juan D.; Saldana, Erick; Cruzado-Bravo, Melina L. M.; Patinho, Iliani; Selani, Miriam M.; Valentin, Dominique; Contreras-Castillo, Carmen J.. Application In Synthesis of Sodium chloride. The article was titled 《Reducing the sodium content without modifying the quality of beef burgers by adding micronized salt》. The information in the text is summarized as follows:

This study determined the effect of the incorporation of micronized salt on physicochem., yield and consumer’s sensory characteristics of beef burger. The micronized salt was obtained by sieving the com. salt in a 60-mesh stainless steel sieve. The com. (regular salt) and micronized salt presented differences in the mean size, size distribution and bulk d. Half of the amount of the micronized salt was mixed with pork back fat, and the other half was added to the meat batter in the beef burger manufacture A Pivot profile method was used with consumers to describe the sensory properties of the burger samples (ranging from 0.5% to 1.5% NaCl). The Pivot profile data revealed that treatments with 0.75% and 0.5% micronized salt were mainly characterized as dry, besides showing the highest cooking loss and diameter reduction However, beef burgers with 1.0% micronized salt and 1.5% regular salt had similar perceived salty taste. In terms of salt reduction, the results indicated that it would be possible to reduce salt from 1.5% to 1.0% when using micronized salt, without affecting the pH, color parameters, yield properties and some sensory characteristics of the burger, such as salty, tasty, juicy, fatty, and spicy. Therefore, this strategy promises great potential for industrial application in products that contain lipids in their composition, such as meat products. The results came from multiple reactions, including the reaction of Sodium chloride(cas: 7647-14-5Application In Synthesis of Sodium chloride)

Sodium chloride(cas: 7647-14-5) has been used for the preparation of tris buffered saline, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation wash buffer, LB (Luria-Bertani) media and dialysis buffer.Application In Synthesis of Sodium chloride

In 2019,Meat Science included an article by Paula, Marielle Maria de Oliveira; Haddad, Gabriela de Barros Silva; Rodrigues, Lorena Mendes; Benevenuto, Augusto Aloisio Junior; Ramos, Alcineia de Lemos Souza; Ramos, Eduardo Mendes. Related Products of 7647-14-5. The article was titled 《Effects of PSE meat and salt concentration on the technological and sensory characteristics of restructured cooked hams》. The information in the text is summarized as follows:

The effects of the use of normal and pale, soft, and exudative (PSE) meat on the technol. and sensorial quality of restructured cooked hams elaborated with different salt contents (0.8, 1.2, 1.6, 2.0, and 2.4%) were investigated. A low salt content implied (P < .05) high cooking loss (6.27 vs 3.25%), expressive moisture and C* values and low hardness. Products elaborated with PSE meat had (P < .05) lower cohesiveness, energy to fracture and hue tone color and higher springiness than did samples elaborated with normal meat. Salty taste perception was slightly higher for the PSE meat-based products, which were also preferred by the assessors when salt contents lower than 1.6% were used. It was concluded that when PSE meat was used, the addition of 1.2% salt was sufficient to maintain the technol. and sensory characteristics of the restructured cooked hams.Sodium chloride(cas: 7647-14-5Related Products of 7647-14-5) was used in this study.

《An incisive optical recognition of monohydrogen phosphate by a fluorescein-based chemodosimeter》 was written by Asthana, Sharad Kumar; Pandey, Abha; Kumar, Ajit; Upadhyay, K. K.. COA of Formula: C3H3ClO3 And the article was included in New Journal of Chemistry in 2020. The article conveys some information:

Numerous methods for the determination of phosphates (H2PO4-, HPO42-, PO43-, PPi) are described in the literature. However, the design of optical probes which are able to recognize specifically monohydrogen phosphate (MHP) ions, i.e. HPO42-, has been rarely considered. We herein devised an incisive chemodosimeter (FLH) for detecting HPO42- over other phosphates successfully. In the experiment, the researchers used Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3COA of Formula: C3H3ClO3)

Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.COA of Formula: C3H3ClO3

In 2022,Ciccone, Lidia; Nencetti, Susanna; Camodeca, Caterina; Ortore, Gabriella; Cuffaro, Doretta; Socci, Simone; Orlandini, Elisabetta published an article in Pharmaceutical Chemistry Journal. The title of the article was 《Synthesis and Evaluation of Monoaryl Derivatives as Transthyretin Fibril Formation Inhibitors》.HPLC of Formula: 622-95-7 The author mentioned the following in the article:

Here, the synthesis of new 2-((benzyloxy)imino)acetic, -propanoic and -butanoic acid derivatives, RCH2ON=C(R1)C(O)OH (R = 2-chlorophenyl, 4-methoxyphenyl, 2,4-dichlorophenyl, etc.; R1 = H, Me, Et) results of their turbidimetric UV assay and the docking study of new monoaryl compounds were reported. The obtained results suggest that, for this class of compounds, (i) the chlorine atom in ortho position on the aromatic ring is the best substituent; (ii) the linker inversion still allows the interaction with thyroxine binding sites; and (iii) the steric hindrance in R1 position is detrimental for the activity. The results came from multiple reactions, including the reaction of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7HPLC of Formula: 622-95-7)
