General description

2,5-Hexanedione is a major metabolite of the neurotoxic industrial solvent methyl n-butyl ketone. It reacts with amines to yield 2,5-dimethylpyrroles.

Application

2,5-Hexanedione was used as starting reagent in the synthesis of trans-2,5-dimethylpyrrolidine.
It was used as reference standard for the determination of 2,5HD in human urine using gas chromatography-electron capture detection and gas chromatography-mass selective detection.

3,4-Dimethyl-2,5-hexanedione and 2,5-hexanedione were reacted with model amines to yield N-substituted 2,3,4,5-tetramethylpyrroles and 2,5-dimethylpyrroles, respectively. When compared to the unsubstituted parent compound 2,5-hexanedione, 3,4-dimethyl-2,5-hexanedione was found to cyclize approximately eight times as rapidly on a molar basis at 37 degrees
