Chemical Structure

1-Ethyl-4-methyl-1h-pyrazole CAS 138948-41-1 chemical structure

Description

Based on its molecular formula C6H10N2, 1-Ethyl-4-methyl-1h-pyrazole contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 110.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
