Tesfaldet, Zeriet O. published the artcileSequential injection spectrophotometric determination of trace amounts of iodide by its catalytic effect on the 4,4′-methylenebis(N,N-dimethylaniline)-chloramine-T reaction, Category: chlorides-buliding-blocks, the publication is Talanta (2004), 64(5), 1213-1219, database is CAplus and MEDLINE.

A simple and sensitive sequential injection spectrophotometric procedure is proposed for the determination of trace amounts of iodide in pharmaceutical preparations The method was based on the catalytic effect of iodide on the (tetra base) 4,4′-methylene bis(N,N-dimethylaniline)chloramine-T reaction in acidic solution The method involves a sequential aspiration of 255 μl sample/standard followed by 170 μl tetra base and then 128 μl chloramine-T solutions into a carrier stream to be stacked inside a holding coil and flow reversed through a reaction coil towards a detector. The resulting colored compound was measured at 600 nm using an UV/Vis-spectrophotometer. All the parameters that affected the reaction were evaluated and the calibration curve was linear over a range of 0.1-6.0 μg l^-1 of iodide concentration with detection limit of 0.05 μg l^-1. A sample throughput of 80 samples per h and relative standard deviation of less than 2.0% was achieved. The method was successfully applied for the determination of iodide in three different samples (tablets).

Stergiopoulos, Chrysanthos published the artcileThe use of biomimetic chromatography to predict acute aquatic toxicity of pharmaceutical compounds, Application of Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Toxicological & Environmental Chemistry (2022), 104(1), 1-19, database is CAplus.

The potential of biomimetic chromatog. to predict ecotoxicol. endpoints of pharmaceutical compounds was investigated. For this purpose, a data set of previously and newly measured chromatog. retention data for 36 structurally diverse drugs was used. Standardized retention times were measured on the immobilized artificial membrane, human serum albumin, and alpha-1-acid glycoprotein stationary phases. As ecotoxicol. endpoints, half-maximal lethal concentration values of fish and half-maximal effective concentration (immobilization) values of a water flea (Daphnia magna spp.) determined with a two-day static method were considered. Ecotoxicity values correlated with octanol-water partitioning and the pos. charge of compounds contributed even more to the toxicity. Models based on membrane partition exhibited the best statistics and predictive performance, attributed to lipophilicity and membrane electrostatic interactions. Alpha-1-acid glycoprotein binding led to satisfactory models, owing to its function as a binder of neutral and basic lipophilic compounds Albumin binding, however, did not result in sound models, as it is governed by lipophilicity and the neg. charge of compounds, contrary to the mechanism of toxicity. Both membrane and alpha-1-acid glycoprotein models were superior statistically from those derived from the octanol-water system. Overall, membrane and alpha-1-acid glycoprotein retention can be suggested as promising indexes to assess the ecotoxicol. risk of drugs.

Seno, Manabu published the artcilePreparation, properties, and x-ray photoelectron spectra of palladium(II) and platinum(II) complexes of amine imides aminimides and sulfur ylides, Recommanded Product: trimethyloxosulphonium chloride, the publication is Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) (1977), 751-7, database is CAplus.

Amine imides RMe2N+N-COR1 (R = PhCH2, p-O2NC6H4CH2; R1 = Me, Et, Ph) and the S ylides Me2S+(O)C-HCOPh with Pd(II) and Pt(II) halides gave ylide-metal complexes PdCl2L2 (L = amine imide), PtCl2[Me2S+(O)C-HCOPh]SEt2, and MCl2[Me2S+(O)C-HCOPh]2 (M = Pd, Pt). IR, 1H and 13C NMR, and x-ray photoelectron spectra indicated that the coordination of the ylide to the metal was through the nucleophilic N+ or C- atom as simple terminal ligands. Cis-PtCl2[Me2S+(O)C-HCOPh]SEt2 released SEt2 in Me2SO giving PtCl2[Me2S+(O)C-HCOPh] which was chelated through the carbanion C and the sulfonium O of the ylide. The thermal properties of the complexes were examined by thermal gravimetric anal. and the nature of the bonding was discussed.

The best separation of trimethylaminobutyrate derivatives[Me3N+(CH2)3CO2RCl-] came when a plate was heated for 1 hr at 120°. Sharp spots free from tailing were found in the solvent system EtOAc-HCO2H-water. Increasing the HCO2H concentration gave higher Rf values, but did not improve separation The Rst values were applied using crystal violet as the standard and the results were better in terms of reproducibility.

Furthermore, an amphiphilic polymeric catalyst prepared from crosslinked polystyrene containing sulfonated groups successfully catalyzed the asym. transfer hydrogenation of cyclic imines in water. Enantioenriched secondary amines with up to 94% ee were obtained by using a polymeric catalyst.
