Methyl acetoacetate

Methyl acetoacetate (CAS 105-45-3), commonly abbreviated as MAA, is a beta-ketoester used across coatings, polymer chemistry, and flavor manufacturing. Acetoacetic acid methyl ester is a recognized alternative name buyers encounter in technical sourcing contexts.

It functions as a reactive intermediate and solvent carrier in industrial formulation. In coatings and printing inks, MAA acts as a crosslinking agent in acetoacetate-functional systems, enabling ambient-cure reactions without isocyanates.

Polymer manufacturers use it as a monomer building block to introduce reactive ester functionality into acrylic and vinyl resins. In flavor formulation, it contributes fruity, rum-like top notes to food products and is used in compounding flavor concentrates.

This chemical is essential for confectionery and beverages. Personal care formulators incorporate it as a fragrance intermediate in the synthesis of aroma chemicals used in finished cosmetic products and various consumer goods.

Methyl acetoacetate is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers. It is offered in technical grade for coatings and polymer applications.

The product is also available in purity grades meeting food and flavor industry specifications. Suppliers typically provide documentation aligned with FCC and FEMA-recognized flavor ingredient requirements for global distribution.
