Compared with other compounds in its class, the molecular weight of 112.09 g/mol gives 1H-1,2,3-triazole-5-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1H-1,2,3-triazole-5-carboxamide (CAS 53897-99-7), molecular formula C3H4N4O and molecular weight 112.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1H-1,2,3-triazole-5-carboxamide (C3H4N4O) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 1H-1,2,3-triazole-5-carboxamide 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.
