Esters have small molecular weight and very nice odor. They are responsible for the pleasant odor of jasmine, roses, etc. and for the odors of apples, bananas, strawberries, etc. The higher the molecular weight, the weaker the odors they carry are.
Unsaturated esters have stronger odor than the saturated ones.

Esters are used in the fragrance and flavoring industries. They also have implication as fixatives and carrier solvents.
