2-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methylbutanoic acid CAS 1490805-38-3 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 2-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methylbutanoic acid.

2-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methylbutanoic acid (CAS 1490805-38-3) is a high-purity analytical reference standard with the molecular formula C9H16O4S and a molecular weight of 220.29 g/mol.

2-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methylbutanoic acid (C9H16O4S) 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.

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.
