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 3-(Pyridin-4-yl)-1H-1,2,4-triazol-5-ol.
CATO supplies 3-(Pyridin-4-yl)-1H-1,2,4-triazol-5-ol (CAS 939-08-2), a certified reference material (molecular formula C7H6N4O, MW 162.15 g/mol) for analytical method development and quality control.
3-(Pyridin-4-yl)-1H-1,2,4-triazol-5-ol (C7H6N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
