Description
CATO manufactures (5-Chloro-3-methylpyridin-2-yl)boronic acid 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.
(5-Chloro-3-methylpyridin-2-yl)boronic acid (CAS 1208314-98-0), molecular formula C6H7BClNO2 and molecular weight 171.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (5-Chloro-3-methylpyridin-2-yl)boronic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
