Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-Chlorophenyl)-5-oxo-N-phenyl-2,5-dihydro-1H-1,2,4-triazole-3-carboxamide (CAS 1000577-29-6) is a high-purity analytical reference standard with the molecular formula C15H11ClN4O2 and a molecular weight of 314.73 g/mol.
1-(2-Chlorophenyl)-5-oxo-N-phenyl-2,5-dihydro-1H-1,2,4-triazole-3-carboxamide (C15H11ClN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-(2-Chlorophenyl)-5-oxo-N-phenyl-2,5-dihydro-1H-1,2,4-triazole-3-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.
