Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4-Methoxy-5-(methoxycarbonyl)-2-methylphenyl)boronic acid (CAS 1332519-32-0), molecular formula C10H13BO5 and molecular weight 224.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Methoxy-5-(methoxycarbonyl)-2-methylphenyl)boronic acid (C10H13BO5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), (4-Methoxy-5-(methoxycarbonyl)-2-methylphenyl)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.
