The molecular framework of 4-(4-(4-Bromophenyl)-5-((naphthalen-1-ylmethyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C24H17BrN4S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-(4-(4-Bromophenyl)-5-((naphthalen-1-ylmethyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 676643-89-3), molecular formula C24H17BrN4S and molecular weight 473.39 g/mol, is a CATO reference standard with documented purity and traceability.
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-(4-Bromophenyl)-5-((naphthalen-1-ylmethyl)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.
