Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-3-(methylsulfonyl)phenylboronic acid pinacol ester.
CATO supplies 4-Fluoro-3-(methylsulfonyl)phenylboronic acid pinacol ester (CAS 1203655-90-6), a certified reference material (molecular formula C13H18BFO4S, MW 300.15 g/mol) for analytical method development and quality control.
4-Fluoro-3-(methylsulfonyl)phenylboronic acid pinacol ester (C13H18BFO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
CATO manufactures 4-Fluoro-3-(methylsulfonyl)phenylboronic acid pinacol ester 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.
