1-(4-Bromophenyl)-3-(4-chlorophenyl)-1H-pyrazol-5-amine CAS 618098-20-7

Description

The occurrence of 1-(4-Bromophenyl)-3-(4-chlorophenyl)-1H-pyrazol-5-amine 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.

1-(4-Bromophenyl)-3-(4-chlorophenyl)-1H-pyrazol-5-amine (CAS 618098-20-7) is a high-purity analytical reference standard with the molecular formula C15H11BrClN3 and a molecular weight of 348.62 g/mol.

Based on its molecular formula C15H11BrClN3, 1-(4-Bromophenyl)-3-(4-chlorophenyl)-1H-pyrazol-5-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 348.62 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.
