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 3-(Ethoxycarbonyl)-1-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1h-pyrazole-5-carboxylic acid (CAS 1264039-96-4), a certified reference material (molecular formula C14H13F3N2O4, MW 330.26 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Ethoxycarbonyl)-1-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1h-pyrazole-5-carboxylic acid (C14H13F3N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 3-(Ethoxycarbonyl)-1-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1h-pyrazole-5-carboxylic acid 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.
