Chemical Structure

(<I>S</I>)-(+)-2-methylbutanesulfonate methyl ester CAS 104418-40-8 chemical structure

Description

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.

(<I>S</I>)-(+)-2-methylbutanesulfonate methyl ester (CAS 104418-40-8), molecular formula C6H14O3S and molecular weight 166.24 g/mol, is a CATO reference standard with documented purity and traceability.

(<I>S</I>)-(+)-2-methylbutanesulfonate methyl ester (C6H14O3S) 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.
