Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3-Methyl-4-nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxamide (CAS 89239-86-1), a certified reference material (molecular formula C7H7F3N4O3, MW 252.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-4-nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxamide (C7H7F3N4O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
