An organic compound formed by the reaction of acetaldehyde with two ethanol molecules; used in organic synthesis and fragrance chemistry.
From 'diethyl' (two ethyl groups) + 'acetal' (a type of organic functional group formed from aldehydes). Acetal comes from 'acetum' (Latin for vinegar) + '-al'.
Diethylacetal is found in some artificial flavorings and fragrances—it's an example of how chemists can recreate natural scents by building specific molecular structures piece by piece.
