2-Oxo-2-((5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)amino)acetic acid CAS 130992-22-2 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 2-Oxo-2-((5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)amino)acetic acid.

CATO supplies 2-Oxo-2-((5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)amino)acetic acid (CAS 130992-22-2), a certified reference material (molecular formula C4H4N4O3S, MW 188.16 g/mol) for analytical method development and quality control.

The molecular framework of 2-Oxo-2-((5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)amino)acetic acid (C4H4N4O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 2-Oxo-2-((5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)amino)acetic 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.
