Isoamyl acetate

CAS: 123-92-2

Overview

Isoamyl acetate (CAS 123-92-2 ), also known as isopentyl acetate, is an ester-based solvent and flavoring agent with a characteristic banana-pear aroma profile. It serves dual commercial roles as a functional solvent in industrial coating and printing applications.

The compound is also a key flavoring ingredient in food and fragrance formulations. In food manufacturing, it delivers banana and pear notes to confectionery, beverages, and baked goods. It is recognized under FEMA 2055 for use in flavor systems.

Printing and packaging operations use it as a fast-evaporating solvent in nitrocellulose-based inks and lacquers. Its evaporation rate supports print quality and adhesion on flexible substrates. Personal care formulators incorporate it into fragrance blends and nail care products.

In these applications, it contributes both scent character and solvent function. It also acts as a carrier solvent in aerosol formulations and specialty coatings requiring controlled viscosity and clean evaporation. This versatility makes it a staple in chemical manufacturing.

Isoamyl acetate is supplied as a clear liquid in drum and IBC quantities. Food-grade material is available meeting FCC specifications, while technical-grade is offered for industrial solvent applications. Purity levels typically range from 98% to 99%+ depending on the end use.
