Propanal

Propionaldehyde or propanal is the organic compound with the formula CH3CHCHO. It is a saturated 3-carbon aldehyde and is a structural isomer of acetone. The parent of the class of propanals. It has a role as an Escherichia coli metabolite.

Definition, An aldehyde that consists of ethane bearing a formyl substituent.
