3-(4-Bromophenyl)-1-methyl-1H-pyrazol-5-ol CAS 160377-46-8

Description

The occurrence of 3-(4-Bromophenyl)-1-methyl-1H-pyrazol-5-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromophenyl)-1-methyl-1H-pyrazol-5-ol (CAS 160377-46-8), molecular formula C10H9BrN2O and molecular weight 253.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H9BrN2O, 3-(4-Bromophenyl)-1-methyl-1H-pyrazol-5-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
