Ethyl Methanethiosulfonate CAS 2043-76-7 chemical structure

Description

Ethyl Methanethiosulfonate (CAS 2043-76-7), molecular formula C3H8O2S2 and molecular weight 140.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl Methanethiosulfonate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

As a certified reference material (CRM), Ethyl Methanethiosulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
