2-(3-Methyl-5-(4-nitrophenyl)-4H-1,2,4-triazol-4-yl)benzoic acid (CAS 648917-55-9), molecular formula C16H12N4O4 and molecular weight 324.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-(3-Methyl-5-(4-nitrophenyl)-4H-1,2,4-triazol-4-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
