Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Nitro-1-{[2-(trifluoromethyl)phenyl]methyl}-1h-pyrazole.
CATO supplies 4-Nitro-1-{[2-(trifluoromethyl)phenyl]methyl}-1h-pyrazole (CAS 1006526-27-7), a certified reference material (molecular formula C11H8F3N3O2, MW 271.20 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-Nitro-1-{[2-(trifluoromethyl)phenyl]methyl}-1h-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
