Description
CATO manufactures 4-(4-Bromo-3-methylphenyl)-2-chloropyridine 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.
4-(4-Bromo-3-methylphenyl)-2-chloropyridine (CAS 1539429-62-3), molecular formula C12H9BrClN and molecular weight 282.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Bromo-3-methylphenyl)-2-chloropyridine (C12H9BrClN) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
