Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-Bromophenyl)-2,4-dihydro-2-phenyl-3h-pyrazol-3-one.

5-(4-Bromophenyl)-2,4-dihydro-2-phenyl-3h-pyrazol-3-one (CAS 59848-48-5) is a high-purity analytical reference standard with the molecular formula C15H11BrN2O and a molecular weight of 315.16 g/mol.

Based on its molecular formula C15H11BrN2O, 5-(4-Bromophenyl)-2,4-dihydro-2-phenyl-3h-pyrazol-3-one 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 315.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
