5-Amino-1-(4-trifluoromethylphenyl)-1H-pyrazole-4-carbonitrile CAS 80025-67-8

Description

Compared with other compounds in its class, the molecular weight of 252.20 g/mol gives 5-Amino-1-(4-trifluoromethylphenyl)-1H-pyrazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Amino-1-(4-trifluoromethylphenyl)-1H-pyrazole-4-carbonitrile (CAS 80025-67-8), a certified reference material (molecular formula C11H7F3N4, MW 252.20 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 5-Amino-1-(4-trifluoromethylphenyl)-1H-pyrazole-4-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.20 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.
