1-(4-Nitrophenyl)-1h-1,2,3-triazole-4-carboxylic acid CAS 4600-06-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Nitrophenyl)-1h-1,2,3-triazole-4-carboxylic acid.

1-(4-Nitrophenyl)-1h-1,2,3-triazole-4-carboxylic acid (CAS 4600-06-0), molecular formula C9H6N4O4 and molecular weight 234.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(4-Nitrophenyl)-1h-1,2,3-triazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.17 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.
