3,4-Dimethyl-5-pyrazolone is a methyl ester that has been stabilized with a carboxy group. It has a mass spectra and infrared spectrum that can be used to identify it. 3,4-Dimethyl-5-pyrazolone is an analog of the methyl ester 2,3,4,5-tetramethylpyrazole and isomeric with 3,4-dimethylpyrazolone. The compound's structure consists of intramolecular hydrogen bonding between the carbonyl oxygen atom and the hydroxyl on the adjacent ring. 3,4-Dimethyl-5-pyrazolone undergoes intramolecular hydrogen bond fragmentation in mass spectroscopy. Fragmentation patterns are unique to each individual compound and can be used to identify it as well as differentiate it from other compounds.
