Chemical Structure
Description
N-(4-((4-isopropylphenyl)amino)-4-oxobutyl)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide (CAS 956543-83-2) is a high-purity analytical reference standard with the molecular formula C19H23F3N4O2 and a molecular weight of 396.41 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-(4-((4-isopropylphenyl)amino)-4-oxobutyl)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
