1,1'-[(1,1-Dimethylethyl)[[(1S)-1-methyl-2-propyn-1-yl]oxy]silylene]bis[benzene] CAS 603045-12-1

Description

1,1'-[(1,1-Dimethylethyl)[[(1S)-1-methyl-2-propyn-1-yl]oxy]silylene]bis[benzene] (CAS 603045-12-1), molecular formula C20H24OSi and molecular weight 308.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,1'-[(1,1-Dimethylethyl)[[(1S)-1-methyl-2-propyn-1-yl]oxy]silylene]bis[benzene] (C20H24OSi) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 308.49 g/mol, it falls into the moderately-high-molecular-weight range. 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 1,1'-[(1,1-Dimethylethyl)[[(1S)-1-methyl-2-propyn-1-yl]oxy]silylene]bis[benzene] 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.
