1-(4-Bromophenyl)-3-phenyl-1H-pyrazol-5(4H)-one CAS 87277-69-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Bromophenyl)-3-phenyl-1H-pyrazol-5(4H)-one.

CATO supplies 1-(4-Bromophenyl)-3-phenyl-1H-pyrazol-5(4H)-one (CAS 87277-69-8), a certified reference material (molecular formula C15H11BrN2O, MW 315.16 g/mol) for analytical method development and quality control.

1-(4-Bromophenyl)-3-phenyl-1H-pyrazol-5(4H)-one (C15H11BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
