Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,4-Dimethylphenyl)-3,5-diphenyl-1H-pyrazole.
1-(2,4-Dimethylphenyl)-3,5-diphenyl-1H-pyrazole (CAS 618442-06-1) is a high-purity analytical reference standard with the molecular formula C23H20N2 and a molecular weight of 324.42 g/mol.
Structurally, 1-(2,4-Dimethylphenyl)-3,5-diphenyl-1H-pyrazole (C23H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 324.42 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
