Description
Compared with other compounds in its class, the molecular weight of 266.22 g/mol gives (3-((Tert-butyldimethylsilyl)oxy)-2-methylphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-((Tert-butyldimethylsilyl)oxy)-2-methylphenyl)boronic acid (CAS 1148021-80-0), a certified reference material (molecular formula C13H23BO3Si, MW 266.22 g/mol) for analytical method development and quality control.
(3-((Tert-butyldimethylsilyl)oxy)-2-methylphenyl)boronic acid (C13H23BO3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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-((Tert-butyldimethylsilyl)oxy)-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.
