Chemical Structure
Description
The occurrence of (1α,3R,4α,5R)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1,4-dihydroxy-cyclohexanecarboxylic Acid Methyl Ester 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.
CATO supplies (1α,3R,4α,5R)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1,4-dihydroxy-cyclohexanecarboxylic Acid Methyl Ester (CAS 135711-62-5), a certified reference material (molecular formula C20H42O6Si2, MW 434.71 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (1α,3R,4α,5R)-3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1,4-dihydroxy-cyclohexanecarboxylic Acid Methyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
