3-(4-Chlorophenyl)-1-(2,4-difluorophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole CAS 478050-14-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Chlorophenyl)-1-(2,4-difluorophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole.

3-(4-Chlorophenyl)-1-(2,4-difluorophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole (CAS 478050-14-5) is a high-purity analytical reference standard with the molecular formula C21H15ClF2N2 and a molecular weight of 368.81 g/mol.

Structurally, 3-(4-Chlorophenyl)-1-(2,4-difluorophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole (C21H15ClF2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 368.81 g/mol, it falls into the moderately-high-molecular-weight range. 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.
