3-(4-bromophenyl)-4-(chloromethyl)-1-phenyl-1H-pyrazole CAS 372107-20-5

Description

The occurrence of 3-(4-bromophenyl)-4-(chloromethyl)-1-phenyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(4-bromophenyl)-4-(chloromethyl)-1-phenyl-1H-pyrazole (CAS 372107-20-5), a certified reference material (molecular formula C16H12BrClN2, MW 347.64 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 3-(4-bromophenyl)-4-(chloromethyl)-1-phenyl-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
