Chemical Structure
Description
Owing to a carbohydrate-derived structure, a sulfone group, 4,4-dioxo-1,4-oxathiepan-6-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
4,4-dioxo-1,4-oxathiepan-6-ol (CAS 319909-10-9) is a high-purity analytical reference standard with the molecular formula C5H10O4S and a molecular weight of 166.20 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.
