The occurrence of 5-Methyl-4-phenyl-4H-1,2,4-triazole-3-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Methyl-4-phenyl-4H-1,2,4-triazole-3-carbaldehyde (CAS 83503-28-0), a certified reference material (molecular formula C10H9N3O, MW 187.20 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-4-phenyl-4H-1,2,4-triazole-3-carbaldehyde (C10H9N3O) 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 its high hydrophobicity (logP), 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-Methyl-4-phenyl-4H-1,2,4-triazole-3-carbaldehyde 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.
