Chemical Structure
Description
(6-Oxo-1,6-dihydropyrazin-2-yl)boronic acid (C4H5BN2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
(6-Oxo-1,6-dihydropyrazin-2-yl)boronic acid (CAS 1225228-86-3), molecular formula C4H5BN2O3 and molecular weight 139.91 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
