Chemical Structure
Description
3-chloro-5-(4-chlorophenyl)-4-methyl-4H-1,2,4-triazole (CAS 1083281-03-1), molecular formula C9H7Cl2N3 and molecular weight 228.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-chloro-5-(4-chlorophenyl)-4-methyl-4H-1,2,4-triazole (C9H7Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 3-chloro-5-(4-chlorophenyl)-4-methyl-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.
