Description
Compared with other compounds in its class, the molecular weight of 209.99 g/mol gives 3-Borono-4-ethoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Borono-4-ethoxybenzoic acid (CAS 1451391-73-3), molecular formula C9H11BO5 and molecular weight 209.99 g/mol, is a CATO reference standard with documented purity and traceability.
3-Borono-4-ethoxybenzoic acid (C9H11BO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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-Borono-4-ethoxybenzoic 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.
