一般描述
2,5-Hexanedione (2,5HD) is a major metabolite of methyl n-butyl ketone. It is neurotoxic in nature and is water soluble.
应用
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.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
