Chemical Structure

3-(Bromomethyl)-5-(difluoromethyl)-1-methyl-1H-pyrazole CAS 2167461-71-2 chemical structure

Description

The occurrence of 3-(Bromomethyl)-5-(difluoromethyl)-1-methyl-1H-pyrazole is closely related to a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(Bromomethyl)-5-(difluoromethyl)-1-methyl-1H-pyrazole (CAS 2167461-71-2), a certified reference material (molecular formula C6H7BrF2N2, MW 225.03 g/mol) for analytical method development and quality control.

Structurally, 3-(Bromomethyl)-5-(difluoromethyl)-1-methyl-1H-pyrazole (C6H7BrF2N2) contains a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 225.03 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
