Description

3-Methylbutanal (CAS 590-86-3 ), also known as isovaleraldehyde, is an aliphatic aldehyde used as a flavoring and fragrance ingredient across food and cosmetic applications. With FEMA number 2692 , it is a recognized flavoring substance that delivers malty, cocoa, and chocolate-like character to finished products in various industries. In food and beverage formulation, it contributes to the development of roasted, malty, and chocolate flavor profiles in confectionery, baked goods, and dairy products. Fragrance houses incorporate it into fine fragrance and personal care formulations where green, fruity, or aldehydic top notes are required for the final scent profile. It also functions as a chemical intermediate in the synthesis of more complex aroma compounds, supporting flavor ingredient manufacturers upstream in the supply chain. Cosmetic formulators use it in shampoos, conditioners, and skin care products where a defined scent profile is part of the product brief and consumer experience. The product is supplied as a clear liquid in standard packaging formats suited to both laboratory-scale and bulk industrial procurement for global distribution. It is available in flavor and fragrance grade, with purity specifications typically at or above 98%. Buyers should confirm compliance with relevant regional flavor regulations.
