General description

2,5-Hexanedione (2,5HD) is a major metabolite of methyl n-butyl ketone. It is neurotoxic in nature and is water soluble.

Application

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.
