Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Dimethyl 1-phenyl-1H-1,2,3-triazole-4,5-dicarboxylate (CAS 17304-69-7), a certified reference material (molecular formula C12H11N3O4, MW 261.23 g/mol) for analytical method development and quality control.
The molecular framework of Dimethyl 1-phenyl-1H-1,2,3-triazole-4,5-dicarboxylate (C12H11N3O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Dimethyl 1-phenyl-1H-1,2,3-triazole-4,5-dicarboxylate 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.
