Chemical Structure

3-(Methylthio)-6-oxo-1,6-dihydro-1,2,4-triazine-5-carboxamide CAS 96259-33-5 chemical structure

Description

The occurrence of 3-(Methylthio)-6-oxo-1,6-dihydro-1,2,4-triazine-5-carboxamide is closely related to an amide group, 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.

3-(Methylthio)-6-oxo-1,6-dihydro-1,2,4-triazine-5-carboxamide (CAS 96259-33-5) is a high-purity analytical reference standard with the molecular formula C5H6N4O2S and a molecular weight of 186.19 g/mol.

The molecular framework of 3-(Methylthio)-6-oxo-1,6-dihydro-1,2,4-triazine-5-carboxamide (C5H6N4O2S) 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. 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-(Methylthio)-6-oxo-1,6-dihydro-1,2,4-triazine-5-carboxamide 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.
