Chemical Structure
Description
5-Bromo-2,3-bis(chloromethyl)pyridine hydrochloride (CAS 1956309-90-2) is a high-purity analytical reference standard with the molecular formula C7H6BrCl2NHCl and a molecular weight of 291.39 g/mol.
The molecular framework of 5-Bromo-2,3-bis(chloromethyl)pyridine hydrochloride (C7H6BrCl2NHCl) is characterized by a nitrile group, chlorine/bromine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 5-Bromo-2,3-bis(chloromethyl)pyridine hydrochloride 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.
