Chemical Structure
Description
The occurrence of 6-Bromo-3-(3-chlorophenyl)-[1,2,4]triazolo[4,3-a]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Bromo-3-(3-chlorophenyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 1418143-39-1), molecular formula C12H7BrClN3 and molecular weight 308.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-3-(3-chlorophenyl)-[1,2,4]triazolo[4,3-a]pyridine (C12H7BrClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 6-Bromo-3-(3-chlorophenyl)-[1,2,4]triazolo[4,3-a]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.
