1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazol-5-amine CAS 324008-97-1

Description

Compared with other compounds in its class, the molecular weight of 337.73 g/mol gives 1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazol-5-amine (CAS 324008-97-1), molecular formula C16H11ClF3N3 and molecular weight 337.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3-Chlorophenyl)-4-(3-(trifluoromethyl)phenyl)-1H-pyrazol-5-amine (C16H11ClF3N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
