Description

Ethyl 2-methylbutyrate (CAS 7452-79-1 ), also known by its FEMA 2443 designation, is a synthetic flavor and fragrance ester used to impart fresh apple, fruity, and green top notes in consumer products. It is a recognized flavoring substance approved for use in food and beverage applications across major regulatory frameworks. In food and beverage manufacturing, it is used to build or enhance apple, pear, and tropical fruit flavor profiles. Common applications include confectionery, beverages, dairy products, and baked goods. Fragrance formulators incorporate it into personal care products including shampoos, body lotions, and fine fragrances where fresh green-fruity character is required. It is also used in tobacco flavoring and functional food formulations where natural fruit character needs to be replicated or reinforced at low use levels. Flavor houses frequently blend it with other esters and aldehydes. This blending helps to construct complex top-note profiles for finished flavor compounds. Ethyl 2-methylbutyrate is supplied as a clear mobile liquid, typically in drum and IBC quantities for industrial buyers. Smaller pack sizes are available for flavor and fragrance laboratories. Food-grade material conforming to FCC and FEMA specifications is the standard commercial offering for global distribution. Purity is generally 98% or higher for flavor-grade material. This high level of purity ensures consistent performance in sensitive formulations across the food, beverage, and cosmetic industries. Contact us for supply of Ethyl 2-methylbutyrate Request Quote
