Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 3-(2-Nitro-4-(trifluoromethyl)phenyl)-1-phenyl-1H-pyrazole (CAS 400083-14-9), a certified reference material (molecular formula C16H10F3N3O2, MW 333.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H10F3N3O2, 3-(2-Nitro-4-(trifluoromethyl)phenyl)-1-phenyl-1H-pyrazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
