Chemical Structure

3-(2,5-Difluorophenyl)-4-methyl-1h-pyrazol-5-amine CAS 1146218-13-4 chemical structure

Description

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.

CATO supplies 3-(2,5-Difluorophenyl)-4-methyl-1h-pyrazol-5-amine (CAS 1146218-13-4), a certified reference material (molecular formula C10H9F2N3, MW 209.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H9F2N3, 3-(2,5-Difluorophenyl)-4-methyl-1h-pyrazol-5-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 209.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
