Chemical Structure

(S)-4-Isopropyl-1,3,2-dioxathiolane 2,2-dioxide CAS 168141-49-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-4-Isopropyl-1,3,2-dioxathiolane 2,2-dioxide.

(S)-4-Isopropyl-1,3,2-dioxathiolane 2,2-dioxide (CAS 168141-49-9) is a high-purity analytical reference standard with the molecular formula C5H10O4S and a molecular weight of 166.20 g/mol.

Structurally, (S)-4-Isopropyl-1,3,2-dioxathiolane 2,2-dioxide (C5H10O4S) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 166.20 g/mol, it falls into the medium-molecular-weight range.

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.
