Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
((Phenylthio)methyl)boronic acid (CAS 67975-88-6) is a high-purity analytical reference standard with the molecular formula C7H9BO2S and a molecular weight of 168.02 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, ((Phenylthio)methyl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures ((Phenylthio)methyl)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.
