Butyl butyryllactate is a diester resulting from the formal condensation of the carboxy group of 2-(butanoyloxy)propanoic acid with butan-1-ol.
Definition
Butyl butyryllactate is a diester resulting from the formal condensation of the carboxy group of 2-(butanoyloxy)propanoic acid with butan-1-ol. It has a role as a flavouring agent and a plant metabolite. It is a butyrate ester and a diester. It is functionally related to a butan-1-ol and a 2-hydroxypropanoic acid.
