Chemical Structure
Description
(3-(3-(4-Nitrophenyl)ureido)phenyl)boronic acid (CAS 397843-84-4), molecular formula C13H12BN3O5 and molecular weight 301.06 g/mol, is a CATO reference standard with documented purity and traceability.
(3-(3-(4-Nitrophenyl)ureido)phenyl)boronic acid (C13H12BN3O5) contains a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (3-(3-(4-Nitrophenyl)ureido)phenyl)boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
