Description
5-(Methoxycarbonyl)thiophene-3-boronic Acid Pinacol Ester (CAS 709648-80-6), molecular formula C12H17BO4S and molecular weight 268.14 g/mol, is a CATO reference standard with documented purity and traceability.
5-(Methoxycarbonyl)thiophene-3-boronic Acid Pinacol Ester (C12H17BO4S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 5-(Methoxycarbonyl)thiophene-3-boronic 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.
