CATO supplies 4-(4-Bromophenyl)-3-((naphthalen-1-ylmethyl)thio)-5-phenyl-4H-1,2,4-triazole (CAS 763139-03-3), a certified reference material (molecular formula C25H18BrN3S, MW 472.40 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-Bromophenyl)-3-((naphthalen-1-ylmethyl)thio)-5-phenyl-4H-1,2,4-triazole (C25H18BrN3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(4-Bromophenyl)-3-((naphthalen-1-ylmethyl)thio)-5-phenyl-4H-1,2,4-triazole 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.
