1-(2,4-Dichlorophenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide CAS 102996-38-3

Description

CATO supplies 1-(2,4-Dichlorophenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide (CAS 102996-38-3), a certified reference material (molecular formula C11H6Cl2F3N3O, MW 324.09 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/chlorine substitution, 1-(2,4-Dichlorophenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.09 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.

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.
