CATO supplies 4-methyl-2-(4H-1,2,4-triazol-3-yl)-1,3-thiazole-5-carboxylic acid (CAS 1258651-75-0), a certified reference material (molecular formula C7H6N4O2S, MW 210.21 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-methyl-2-(4H-1,2,4-triazol-3-yl)-1,3-thiazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.21 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
