Description

Methyl isobutyrate (CAS 547-63-7 ), also identified under FEMA 2694 , is an ester used commercially as both a flavoring ingredient and a specialty solvent. It delivers a characteristic sweet, fruity, apple-like note. This chemical makes it a recognized building block in flavor and fragrance creation. In food and beverage formulations, it contributes fruity top notes to confectionery, baked goods, and dairy-flavored products. It is particularly useful where a light, fresh character is required. Fragrance compounders incorporate it into personal care products, including shampoos, lotions, and body sprays, to add brightness to fruity or green accords. As a solvent, it supports the dissolution and delivery of fragrance concentrates and flavor extracts in both aqueous and non-aqueous systems. Its low residual profile makes it a candidate carrier in cosmetic formulations. This is especially true where solvent odor interference must be minimized. Methyl isobutyrate is supplied as a clear liquid in drum and IBC quantities suited to industrial procurement volumes for large scale manufacturing. Food-grade material conforming to FEMA 2694 status is the primary commercial specification, meeting purity requirements for flavor applications. Technical-grade material is also available for solvent and fragrance manufacturing. These grades are utilized where food compliance is not required. Our supply chain ensures consistent quality and availability for global distribution to chemical manufacturers and flavor houses across the industry.
