Esteve-Turrillas, F. A.; Mercader, J. V.; Agullo, C.; Abad-Somovilla, A.; Abad-Fuentes, A. published an article in 2017, the title of the article was A class-selective immunoassay for simultaneous analysis of anilinopyrimidine fungicides using a rationally designed hapten.SDS of cas: 35444-44-1 And the article contains the following content:

The development of multianalyte immunoassays constitutes a main research issue in the field of bioanal. techniques. In the present study, class-specific antibodies against the three members of the anilinopyrimidine family of fungicides (pyrimethanil, cyprodinil and mepanipyrim) were raised by using a bioconjugate of a rationally designed hapten [5-(6-methyl-2-(phenylamino)pyrimidin-4-yl)pentanoic acid]. Highly sensitive immunoassays were developed for the generic determination of these compounds, using the competitive ELISA (ELISA). Particularly, a direct antibody-coated competitive ELISA afforded identical sensitivity for the three anilinopyrimidines, with IC50 values of 0.26, 0.27 and 0.25 μg L-1 for pyrimethanil, cyprodinil and mepanipyrim, resp. This immunoassay was fully characterized and applied to the multianalyte determination of anilinopyrimidine fungicides in white and red wines, with a limit of quantification of 1 μg L-1, average recoveries from 93.1 to 114.4%, and relative standard deviations lower than 20%. Com. wine samples were analyzed and those containing detectable anilinopyrimide residues were verified by a reference chromatog. technique. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).SDS of cas: 35444-44-1

da Rocha, Caroline O.; Petruci, Joao Flavio S.; Cardoso, Arnaldo A. published an article in 2017, the title of the article was Methylene violet 3 RAX dye as a new reagent for the determination of nitrite in cured meats and vegetables.Electric Literature of 4569-86-2 And the article contains the following content:

In this contribution we propose, for the first time, the use of Methylene Violet 3 RAX dye for the detection and determination of nitrite in cured meats and vegetables. Quantification is based on the decrease in absorbance of the dye, which is proportional to the nitrite concentration The proposed method presents linear response (r > 0.99) in the range from 1.8 to 9 μmol L-1 of nitrite, with a limit of detection of 0.14 μmol L-1. Satisfactory accuracy with the official Association of Official Agricultural Chemists (AOAC) method was achieved, and the method was successfully applied to a wide range of cured meats and vegetables. The proposed method offers similar or superior performance to other optical methods used for the determination of nitrite in different matrixes, with advantage in terms of reduction of chem. waste for each anal., by minimizing amounts of reagents and products. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Electric Literature of 4569-86-2

On October 31, 1983, Naganuma, Masayuki; Ohtsu, Yutaka; Katsumura, Yoshio; Matsuoka, Masahiro; Morikawa, Yoshihiro; Tanaka, Muneo; Mitsui, Takeo published an article.Category: chlorides-buliding-blocks The title of the article was Analysis of subsidiary colors in Red Number 204 and its purification. Development of non-allergenic Red Number 204. And the article contained the following:

Red Number 204 (Lake Red CBA) [5160-02-1], used for make-up products including lipstick, was analyzed for its organic impurities. These impurities were isolated by high-performance liquid chromatog. and their structural formulas were confirmed by various anal. methods. Many kinds of aromatic azo compounds (subsidiary colors) were found. The subsidiary colors were 11 kinds including Sudan 1. These subsidiary colors and the related compounds were synthesized for use as the standard samples. The subsidiary colors in Lake Red CBA showed pos. results with the modified guinea pig maximization test indicating that each of them was a contact sensitizer, while Lake Red CBA itself was not. Lake Red CBA synthesized with C acid  [88-53-9] from which aromatic amines were removed contained no subsidiary color. When Lake Red CBA was synthesized with the purified C acid to which 3 types of the typical aromatic amines were added in fixed quantity, the corresponding aromatic azo compounds were produced in proportion to the added amounts of aromatic amines. The preparation of Sudan III, Orange II, Quinoline Yellow WS, Quinizarin Green SS, etc., free from contact sensitive impurities, for use in cosmetic products is discussed. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Category: chlorides-buliding-blocks

Tobiszewski, Marek; Namiesnik, Jacek; Pena-Pereira, Francisco published an article in 2017, the title of the article was A derivatisation agent selection guide.Recommanded Product: (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate And the article contains the following content:

The study reported herein is aimed at the greenness assessment of 267 derivatization agents that are frequently applied in anal. chem. and related disciplines. Multicriteria decision anal. allowed obtaining three rankings of derivatization agents applied in liquid chromatog., gas chromatog. and chiral anal. The criteria of assessment included the safety information obtained from material safety data sheets and physicochem. and environmental parameters predicted with relevant models. As for some of the agents predicted data were not available, these agents were assessed with a smaller number of criteria, within the ranking of low confidence. The results of the study will help to apply greener derivatization agents, wherever the green chem. principle of avoiding derivatization cannot be fulfilled. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Recommanded Product: (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate
