Chemical Structure

3-Methyl-5-phenyl-4,5-dihydro-1H-pyrazole CAS 939-03-7 chemical structure

Description

3-Methyl-5-phenyl-4,5-dihydro-1H-pyrazole (C10H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
