CATO supplies 3-(4-Fluorophenyl)-6-(4-(trifluoromethyl)benzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (CAS 892480-74-9), a certified reference material (molecular formula C18H11F4N5O, MW 389.31 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Fluorophenyl)-6-(4-(trifluoromethyl)benzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (C18H11F4N5O) 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.
