CATO supplies 4-(4-Nitrobenzyl)-7-oxo-2-(trifluoromethyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid (CAS 1135989-39-7), a certified reference material (molecular formula C14H8F3N5O5, MW 383.24 g/mol) for analytical method development and quality control.
4-(4-Nitrobenzyl)-7-oxo-2-(trifluoromethyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid (C14H8F3N5O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.
