Description
Ethyl acetoacetate (CAS 141-97-9), also known as acetoacetic ester, acetoacetic ether, and diacetic ether, is a beta-ketoester compound with the molecular formula C6H10O3. It carries no assigned E-code and is commercially identified under EC number 205-516-1 and HS code 29183000.
In food and fragrance applications, ethyl acetoacetate delivers a characteristic fruity, rum-like note and functions as a flavorant at low concentrations in finished products. In coatings and adhesive systems, its active methylene group enables crosslinking reactions with isocyanates or amines, building polymer network density and improving substrate adhesion.
Ethyl acetoacetate is available in technical and food-grade qualities, with food-grade material conforming to FCC specifications. It falls under REACH regulation and requires an up-to-date Safety Data Sheet for EU trade. Standard packaging includes drums and IBCs, with bulk quantities available subject to supplier confirmation.
