Chemical Structure
Description
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.
((1R,2R)-2-(((tert-Butyldiphenylsilyl)oxy)methyl)cyclobutyl)methanol (CAS 2130069-75-7), molecular formula C22H30O2Si and molecular weight 354.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, ((1R,2R)-2-(((tert-Butyldiphenylsilyl)oxy)methyl)cyclobutyl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.56 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.
As a certified reference material (CRM), ((1R,2R)-2-(((tert-Butyldiphenylsilyl)oxy)methyl)cyclobutyl)methanol 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.
