5-Amino-1-phenyl-1H-1,2,3-triazole-4-carboxamide (CAS 20317-25-3) is a high-purity analytical reference standard with the molecular formula C9H9N5O and a molecular weight of 203.20 g/mol.
The molecular framework of 5-Amino-1-phenyl-1H-1,2,3-triazole-4-carboxamide (C9H9N5O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-Amino-1-phenyl-1H-1,2,3-triazole-4-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.
