4-(2-bromophenyl)-3-methyl-1H-pyrazole CAS 1368048-62-7

Description

The occurrence of 4-(2-bromophenyl)-3-methyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(2-bromophenyl)-3-methyl-1H-pyrazole (CAS 1368048-62-7), molecular formula C10H13BrN2 and molecular weight 241.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H13BrN2, 4-(2-bromophenyl)-3-methyl-1H-pyrazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
