4-Oxo-4,7-dihydro-3h-pyrrolo[2,3-d][1,2,3]triazine-5-carboxamide CAS 355375-82-5 chemical structure

Description

CATO manufactures 4-Oxo-4,7-dihydro-3h-pyrrolo[2,3-d][1,2,3]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.

4-Oxo-4,7-dihydro-3h-pyrrolo[2,3-d][1,2,3]triazine-5-carboxamide (CAS 355375-82-5), molecular formula C6H5N5O2 and molecular weight 179.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Oxo-4,7-dihydro-3h-pyrrolo[2,3-d][1,2,3]triazine-5-carboxamide (C6H5N5O2) is characterized by an amino-acid-derived structure, an amide 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.
