Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.28 g/mol gives (Dimethylphenylsilyl)pinacol borate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(Dimethylphenylsilyl)pinacol borate (CAS 185990-03-8), molecular formula C14H29BO2Si and molecular weight 268.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (Dimethylphenylsilyl)pinacol borate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
