Definition
Hexanal is a saturated fatty aldehyde that is hexane in which one of the terminal methyl group has been mono-oxygenated to form the corresponding aldehyde. It has a role as a human urinary metabolite. It is a n-alkanal, a saturated fatty aldehyde and a medium-chain fatty aldehyde. It derives from a hydride of a hexane.
