5-methyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-3-amine hydrochloride CAS 1909326-85-7

Description

The occurrence of 5-methyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-3-amine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-methyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-3-amine hydrochloride (CAS 1909326-85-7), a certified reference material (molecular formula C11H10F3N3HCl, MW 277.67 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H10F3N3HCl, 5-methyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-3-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
