Chemical Structure

1,3-oxathiolane CAS 2094-97-5 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 1,3-oxathiolane.

1,3-oxathiolane (CAS 2094-97-5) is a high-purity analytical reference standard with the molecular formula C3H6OS and a molecular weight of 90.14 g/mol.

Structurally, 1,3-oxathiolane (C3H6OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 90.14 g/mol, it falls into the low-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.
