Butyl formate is a formate ester resulting from the formal condensation of formic acid with the hydroxy group of butan-1-ol.
Definition
Butyl formate is a formate ester resulting from the formal condensation of formic acid with the hydroxy group of butan-1-ol. Found in apples, strawberries, sherry and Pamesan cheese, it has a fruity, plum-like odour and taste. It has a role as a flavouring agent, a fragrance and a polar aprotic solvent.
