Chemical Structure

2-sulfanylethanesulfonic acid CAS 3375-50-6 chemical structure

Description

CATO supplies 2-sulfanylethanesulfonic acid (CAS 3375-50-6), a certified reference material (molecular formula C2H6O3S2, MW 142.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C2H6O3S2, 2-sulfanylethanesulfonic acid contains a sulfone group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 142.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
