Chemical Structure
Description
The occurrence of (3AS,4S,6S,6aR)-6-((R)-1-((tert-butyldimethylsilyl)oxy)ethyl)-2,2-dimethyltetrahydro-4H-cyclopenta[d][1,3]dioxol-4-ol 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.
(3AS,4S,6S,6aR)-6-((R)-1-((tert-butyldimethylsilyl)oxy)ethyl)-2,2-dimethyltetrahydro-4H-cyclopenta[d][1,3]dioxol-4-ol (CAS 1638744-62-3) is a high-purity analytical reference standard with the molecular formula C16H32O4Si and a molecular weight of 316.51 g/mol.
The molecular framework of (3AS,4S,6S,6aR)-6-((R)-1-((tert-butyldimethylsilyl)oxy)ethyl)-2,2-dimethyltetrahydro-4H-cyclopenta[d][1,3]dioxol-4-ol (C16H32O4Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
