Description
CATO manufactures 3-Chloro-2,4-difluoropyridine 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.
CATO supplies 3-Chloro-2,4-difluoropyridine (CAS 851179-01-6), a certified reference material (molecular formula C5H2ClF2N, MW 149.53 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/chlorine substitution, 3-Chloro-2,4-difluoropyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
