3-(4-Chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole (CAS 59074-26-9), molecular formula C15H13ClN2 and molecular weight 256.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole (C15H13ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
