Chemical Structure

Ethanesulfonothioic O-acid CAS 51554-68-8 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.

Ethanesulfonothioic O-acid (CAS 51554-68-8), molecular formula C2H6O2S2 and molecular weight 126.20 g/mol, is a CATO reference standard with documented purity and traceability.

Ethanesulfonothioic O-acid (C2H6O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
