Chemical Structure
Description
(2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]-1-butanol (CAS 1309610-41-0), molecular formula C20H28O2Si and molecular weight 328.52 g/mol, is a CATO reference standard with documented purity and traceability.
(2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]-1-butanol (C20H28O2Si) 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), (2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]-1-butanol 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.
