Description
Isobutyl isobutyrate (CAS 97-85-8) is an ester produced by the reaction of isobutanol and isobutyric acid. It carries the FEMA designation 2189 and is also referenced as NSC 6538 and isobutyl isobutanoate. No E-code applies to this ingredient.
In food and beverage formulations, it delivers fruity, apple-like flavor notes and is used at low concentrations to build or enhance fruit flavor profiles in confectionery, beverages, and dairy products. In personal care, it functions as a fragrance component, contributing fresh, sweet top notes to fine fragrances and rinse-off products.
Isobutyl isobutyrate is available as a clear liquid in food-grade quality conforming to FCC specifications and is subject to REACH registration within the EU. It is supplied in standard drum and IBC formats. Procurement teams should confirm FEMA GRAS status and regional flavor regulation compliance prior to use.
