Chemical Structure
Description
1-(4-Fluorophenyl)-N-(4-methoxyphenyl)-5-methyl-1h-1,2,4-triazole-3-carboxamide (CAS 338398-13-3), molecular formula C17H15FN4O2 and molecular weight 326.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Fluorophenyl)-N-(4-methoxyphenyl)-5-methyl-1h-1,2,4-triazole-3-carboxamide (C17H15FN4O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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), 1-(4-Fluorophenyl)-N-(4-methoxyphenyl)-5-methyl-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.
