Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-(4-Bromophenyl)-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine.
3-(4-(4-Bromophenyl)-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477333-41-8), molecular formula C21H17BrN4S and molecular weight 437.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-(4-Bromophenyl)-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C21H17BrN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 3-(4-(4-Bromophenyl)-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
