Chemical Structure
Description
(4S)-4-ethyl-1,3,2-dioxathiolane 2,2-dioxide (CAS 167074-05-7) is a high-purity analytical reference standard with the molecular formula C4H8O4S and a molecular weight of 152.17 g/mol.
Owing to a carbohydrate-derived structure, a sulfone group, (4S)-4-ethyl-1,3,2-dioxathiolane 2,2-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.17 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.
