5-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole hydrochloride CAS 1803604-92-3

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 5-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole hydrochloride (CAS 1803604-92-3), a certified reference material (molecular formula C6H7F3N2HCl, MW 200.59 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H7F3N2HCl, 5-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole hydrochloride contains a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 200.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
