Description

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.
