Description
Ethyl 2-methylbutyrate (CAS 7452-79-1, FEMA 2443) is a naturally occurring ester found in fruits such as apples and strawberries, also identified as ethyl 2-methylbutanoate or ethyl DL-2-methylbutyrate. It carries no assigned E-code and is regulated under REACH in the European market.
In food and beverage formulation, it delivers a fresh, apple-like fruity note at use levels typically between 1 and 10 ppm, functioning as a top-note modifier in flavour systems for confectionery, dairy, and beverages. In personal care, it acts as an emollient and fragrance component, contributing to skin-feel and scent profile in leave-on and rinse-off products.
Ethyl 2-methylbutyrate is supplied as a food-grade liquid meeting FCC specifications, with natural-grade variants available for clean-label applications. It is fully REACH-registered and classified under HS code 29159080. Standard packaging includes drums and intermediate bulk containers, with smaller quantities available on request.
