4-Chloro-N-(4-(1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenyl)benzamide CAS 223499-92-1

Description

4-Chloro-N-(4-(1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenyl)benzamide (CAS 223499-92-1), molecular formula C18H13ClF3N3O and molecular weight 379.76 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-Chloro-N-(4-(1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenyl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.76 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
