Overview
Ethyl acetoacetate ( CAS 141-97-9 ), commonly abbreviated as EAA, is a beta-ketoester used as a reactive intermediate and flavoring agent across coatings, food, and personal care industries.
FEMA 2415 status confirms its recognized use as a flavoring substance in food applications. In coatings and adhesives, EAA functions as a crosslinking agent for acetoacetate-functional resins.
This enables ambient-cure systems in waterborne architectural and industrial coatings. Food manufacturers use it as a flavoring ingredient to impart butter, fruit, and rum-like notes in baked goods.
It is also utilized in confectionery and beverages. In personal care formulations, it contributes fragrance character to creams, lotions, and rinse-off products for various consumer applications.
Pharmaceutical and agrochemical synthesis also draws on EAA as a building block for heterocyclic intermediates and active ingredient production. It is supplied as a clear liquid in drum and IBC quantities.
Bulk tanker options are available for high-volume industrial buyers. Standard commercial grades meet technical and industrial specifications suitable for coatings and synthesis applications.
Food-grade material conforming to FCC requirements is available for flavoring use. Buyers should confirm grade suitability against their specific formulation or regulatory requirements.
