Description
As a certified reference material (CRM), 3-(tert-Butyldimethylsilyloxy)phenylboronic 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.
3-(tert-Butyldimethylsilyloxy)phenylboronic Acid (CAS 261621-12-9), molecular formula C12H21BO3Si and molecular weight 252.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(tert-Butyldimethylsilyloxy)phenylboronic Acid (C12H21BO3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
