Chemical Structure

Mercaptoacetic Acid CAS 68-11-1 chemical structure

Description

The occurrence of Mercaptoacetic Acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Mercaptoacetic Acid (CAS 68-11-1), molecular formula C2H4O2S and molecular weight 92.12 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, Mercaptoacetic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 92.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Mercaptoacetic Acid 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.
