Chemical Structure

4-Methyl-1,2-oxathiolane 2,2-Dioxide CAS 15606-89-0 chemical structure

Description

CATO supplies 4-Methyl-1,2-oxathiolane 2,2-Dioxide (CAS 15606-89-0), a certified reference material (molecular formula C4H8O3S, MW 136.17 g/mol) for analytical method development and quality control.

4-Methyl-1,2-oxathiolane 2,2-Dioxide (C4H8O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
