Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Methylsulfonyl)phenylboronic Acid Pinacol Ester.
CATO supplies 3-(Methylsulfonyl)phenylboronic Acid Pinacol Ester (CAS 1001185-88-1), a certified reference material (molecular formula C13H19BO4S, MW 282.16 g/mol) for analytical method development and quality control.
3-(Methylsulfonyl)phenylboronic Acid Pinacol Ester (C13H19BO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 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.
