Amyl Acetate, specifically n-pentyl acetate (CAS: 628-63-7), is an organic ester produced through the esterification of n-pentanol with acetic acid. It is a clear, colorless liquid characterized by a distinct, sweet odor reminiscent of bananas or pears, leading to its colloquial designation as “banana oil.” As a medium-boiling solvent, it occupies a critical niche in industrial chemistry due to its ability to dissolve a wide range of resins, polymers, and oils.
Chemically, it belongs to the acetate ester family, exhibiting moderate volatility and low water solubility, while remaining highly miscible with most organic solvents. Its primary industrial value lies in its role as a high-performance solvent for nitrocellulose, celluloid, and various lacquers. Beyond its solvency, it serves as a crucial flavoring and fragrance agent in the food and cosmetic industries. Because it evaporates more slowly than lower-order acetates (like ethyl or butyl acetate), it is often employed to control drying times and prevent surface defects in high-end coatings and finishes.
