4-(difluoromethyl)-1H-pyrazole CAS 1211589-69-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(difluoromethyl)-1H-pyrazole.

CATO supplies 4-(difluoromethyl)-1H-pyrazole (CAS 1211589-69-3), a certified reference material (molecular formula C4H8F2N2, MW 122.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H8F2N2, 4-(difluoromethyl)-1H-pyrazole contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 122.12 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.

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.
