Chemical Structure

(3S,5S)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-hydroxy-cyclohexanemethanol CAS 139356-34-6 chemical structure

Description

The occurrence of (3S,5S)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-hydroxy-cyclohexanemethanol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3S,5S)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-hydroxy-cyclohexanemethanol (CAS 139356-34-6) is a high-purity analytical reference standard with the molecular formula C19H42O4Si2 and a molecular weight of 390.71 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (3S,5S)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-hydroxy-cyclohexanemethanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.71 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.

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.
