Chemical Structure
Description
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, (2R,3S,4S)-3,4-Bis(benzyloxy)-2-((benzyloxy)methyl)tetrahydrothiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(2R,3S,4S)-3,4-Bis(benzyloxy)-2-((benzyloxy)methyl)tetrahydrothiophene (CAS 187590-77-8) is a high-purity analytical reference standard with the molecular formula C26H28O3S and a molecular weight of 420.56 g/mol.
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.
