Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 294.27 g/mol gives 4-(Triisopropylsilyloxy)phenyl boronic acid, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Triisopropylsilyloxy)phenyl boronic acid, 97% (CAS 643090-93-1), a certified reference material (molecular formula C15H27BO3Si, MW 294.27 g/mol) for analytical method development and quality control.
4-(Triisopropylsilyloxy)phenyl boronic acid, 97% (C15H27BO3Si) contains a carboxylic acid group, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
