CATO supplies 3-(Ethoxycarbonyl)-5-methyl-1-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1h-pyrazole-5-carboxylic acid (CAS 1264046-90-3), a certified reference material (molecular formula C15H15F3N2O4, MW 344.29 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Ethoxycarbonyl)-5-methyl-1-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1h-pyrazole-5-carboxylic acid (C15H15F3N2O4) is characterized by a flavonoid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
