Chemical Structure

3-(Carboxymethylthio)-2-oxopropanoic acid CAS 51783-05-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Carboxymethylthio)-2-oxopropanoic acid.

CATO supplies 3-(Carboxymethylthio)-2-oxopropanoic acid (CAS 51783-05-2), a certified reference material (molecular formula C5H6O5S, MW 178.16 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, a sulfone group, 3-(Carboxymethylthio)-2-oxopropanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 3-(Carboxymethylthio)-2-oxopropanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
