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.

Chronic exposure of rats to 2,5-hexanedione (CH3COCH2CH2COCH3), a major metabolite of the neurotoxic industrial solvent methyl n-buryl ketone (CH3COCH2CH2CH2CH3), has been shown to cause a clinical peripheral neuropathy with dying-back peripheral and central nervous system degeneration characterized by giant axonal

Sertoli cells are essential for testicular germ cell maintenance and survival. We made the unexpected observation that x-radiation (x-ray)-induced germ cell loss is attenuated by co-exposure with the Sertoli cell toxicant 2,5-hexanedione (HD). The mechanisms underlying this attenuation of germ

The enantiopure (2S,5S)-hexanediol serves as a versatile building block for the production of various fine chemicals and pharmaceuticals. For industrial and commercial scale, the diol is currently obtained through bakers' yeast-mediated reduction of 2,5-hexanedione. However, this process suffers from its

In the testis, developing germ cells are dependent on supportive physical and paracrine interactions with Sertoli cells. The intimate nature of this relationship is demonstrated by the fact that a toxic insult compromising the stability of Sertoli cells will have
