Chemical Structure
Description
CATO supplies 4-(5-Mercapto-4-(m-tolyl)-4H-1,2,4-triazol-3-yl)phenol (CAS 917747-25-2), a certified reference material (molecular formula C15H13N3OS, MW 283.35 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-(5-Mercapto-4-(m-tolyl)-4H-1,2,4-triazol-3-yl)phenol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.35 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.
