Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-{[1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]formamido}-N-[(4-methylphenyl)methyl]butanamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 4-{[1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]formamido}-N-[(4-methylphenyl)methyl]butanamide (CAS 956959-91-4), a certified reference material (molecular formula C18H21F3N4O2, MW 382.38 g/mol) for analytical method development and quality control.
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.
