The occurrence of 3-(Thiazol-2-yl)-1h-pyrazole-4-carboxylic acid is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-(Thiazol-2-yl)-1h-pyrazole-4-carboxylic acid (CAS 1489142-70-2), a certified reference material (molecular formula C7H5N3O2S, MW 195.20 g/mol) for analytical method development and quality control.
3-(Thiazol-2-yl)-1h-pyrazole-4-carboxylic acid (C7H5N3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
