2-(2-Methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylic acid CAS 1368051-28-8 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 2-(2-Methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylic acid.

2-(2-Methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylic acid (CAS 1368051-28-8), molecular formula C14H11N3O3 and molecular weight 269.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-(2-Methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.26 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).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
