Description
CATO manufactures (3,5-Difluoropyridin-4-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.
CATO supplies (3,5-Difluoropyridin-4-yl)boronic acid (CAS 956003-87-5), a certified reference material (molecular formula C5H4BF2NO2, MW 158.90 g/mol) for analytical method development and quality control.
(3,5-Difluoropyridin-4-yl)boronic acid (C5H4BF2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
