Chemical Structure

1H-Pyrazole-5-carboxylic acid, 3-(4-chlorophenyl)-1-[2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl]-4-[[(trifluoromethyl)sulfonyl]oxy]-, ethyl ester CAS 1956364-75-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-Pyrazole-5-carboxylic acid, 3-(4-chlorophenyl)-1-[2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl]-4-[[(trifluoromethyl)sulfonyl]oxy]-, ethyl ester.

CATO supplies 1H-Pyrazole-5-carboxylic acid, 3-(4-chlorophenyl)-1-[2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl]-4-[[(trifluoromethyl)sulfonyl]oxy]-, ethyl ester (CAS 1956364-75-2), a certified reference material (molecular formula C20H23ClF3N3O7S, MW 541.93 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1H-Pyrazole-5-carboxylic acid, 3-(4-chlorophenyl)-1-[2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl]-4-[[(trifluoromethyl)sulfonyl]oxy]-, ethyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 541.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
