Chemical Structure
Description
The occurrence of 2-((Tert-butyldiphenylsilyl)oxy)ethan-1-ol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((Tert-butyldiphenylsilyl)oxy)ethan-1-ol (CAS 138499-16-8) is a high-purity analytical reference standard with the molecular formula C18H24O2Si and a molecular weight of 300.47 g/mol.
2-((Tert-butyldiphenylsilyl)oxy)ethan-1-ol (C18H24O2Si) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-((Tert-butyldiphenylsilyl)oxy)ethan-1-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
