Allyl acetoacetate

Allyl acetoacetate (CAS 1118-84-9), also known as allyl acetylacetate, is a reactive ester used as a chemical intermediate and flavoring agent across pharmaceutical, cosmetic, and food industries. Its dual functionality, combining an active methylene group with a polymerizable allyl moiety, makes it a building block for synthesis and a carrier in formulated products.

In pharmaceutical manufacturing, it serves as a synthetic intermediate for active pharmaceutical ingredients where controlled reactivity at the methylene position is required for complex synthesis. Flavor and fragrance formulators incorporate it into compositions targeting fruity, herbaceous, or green scent profiles, particularly in fine fragrance and food flavoring applications.

Cosmetic chemists use it as a carrier and reactive component in skin-care and hair-care formulations where controlled release or film-forming properties are needed for performance. It also functions as a crosslinking or co-monomer component in specialty polymer and resin systems, providing versatility for industrial material science and chemical engineering projects.

Allyl acetoacetate is supplied as a clear to pale yellow liquid in standard drum and IBC packaging suited to industrial procurement volumes and global logistics requirements. Technical and reagent-grade specifications are the most commonly available, with purity levels typically at 97% or higher. Buyers should confirm compliance with relevant FEMA codes.
