isoamyyliasetaatti

Isoamyyliasetaatti, known in English as isoamyl acetate (isopentyl acetate), is an organic ester formed from isoamyl alcohol (3-methyl-1-butanol) and acetic acid. It is a colorless to pale liquid with a characteristic fruity odor reminiscent of bananas, and it is widely used as a flavor and fragrance compound. In industry and commerce it is often referred to as a banana flavor or aroma constituent, due to its strong fruity note.

Chemically, isoamyl acetate is relatively nonpolar and is more soluble in organic solvents than in water. It participates in standard esterification reactions and is typically produced by acid-catalyzed condensation of isoamyl alcohol with acetic acid, or by transesterification processes. The compound also occurs naturally in several fruits and in trace amounts in fermented products, where it contributes to their aroma profiles.

Applications of isoamyl acetate are concentrated in the flavor and fragrance sectors. It is a principal ingredient in banana-flavored products and is used to impart fruity notes in candies, beverages, dairy products, and baked goods. Beyond flavors, it serves as a solvent or blending component in some coatings, inks, and cosmetic formulations, where its volatility and aroma can be advantageous. It is generally used in small quantities due to its potent scent.

Safety and regulation: isoamyl acetate is flammable and can irritate the skin, eyes, and respiratory tract upon exposure. It should be handled with appropriate ventilation and protective equipment, and stored away from heat sources. In many jurisdictions it is regulated as a flavoring agent or fragrance ingredient, with usage limits in foods and consumer products established by food safety and cosmetic authorities.
