Chemical Structure
Description
CATO manufactures (2-(Methylsulfonamido)pyrimidin-5-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.
(2-(Methylsulfonamido)pyrimidin-5-yl)boronic acid (CAS 1256345-71-7), molecular formula C5H8BN3O4S and molecular weight 217.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, (2-(Methylsulfonamido)pyrimidin-5-yl)boronic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.01 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
