Description
CATO manufactures 3-Bromo-2-chloro-6-ethynylpyridine 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.
3-Bromo-2-chloro-6-ethynylpyridine (CAS 1256808-39-5), molecular formula C7H3BrClN and molecular weight 216.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-2-chloro-6-ethynylpyridine (C7H3BrClN) is characterized by a nitrile group, chlorine/bromine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
