Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 380.55 g/mol gives 1-Phenyl-2-(triphenylsilyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Phenyl-2-(triphenylsilyl)ethanol (CAS 18790-80-2), molecular formula C26H24OSi and molecular weight 380.55 g/mol, is a CATO reference standard with documented purity and traceability.
1-Phenyl-2-(triphenylsilyl)ethanol (C26H24OSi) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
