Chemical Structure
Description
The molecular framework of 3-(2-Methoxy-3,5-dimethylphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C19H18N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. 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).
3-(2-Methoxy-3,5-dimethylphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 618098-89-8) is a high-purity analytical reference standard with the molecular formula C19H18N2O2 and a molecular weight of 306.36 g/mol.
