Chemical Structure

3-Mercaptopyruvic acid CAS 2464-23-5 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-Mercaptopyruvic acid.

3-Mercaptopyruvic acid (CAS 2464-23-5), molecular formula C3H4O3S and molecular weight 120.13 g/mol, is a CATO reference standard with documented purity and traceability.

3-Mercaptopyruvic acid (C3H4O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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-Mercaptopyruvic 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.
