Chemical Structure

5-Methyl-1-phenyl-1H-pyrazole CAS 6831-91-0 chemical structure

Description

5-Methyl-1-phenyl-1H-pyrazole (C10H10N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
