Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 310.20 g/mol gives 3-(Benzyloxy)phenylboronic Acid Pinacol Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Benzyloxy)phenylboronic Acid Pinacol Ester (CAS 765908-38-1), molecular formula C19H23BO3 and molecular weight 310.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Benzyloxy)phenylboronic Acid Pinacol Ester (C19H23BO3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(Benzyloxy)phenylboronic Acid Pinacol Ester 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.
