Description
Diethyl succinate (CAS 123-25-1, EC 204-612-0) is a diethyl ester of succinic acid, commonly abbreviated as DESU and also known by trade references FEMA 2377 and NSC 8875. It carries no E-code designation and is commercially identified under the synonym ethyl succinate.
In food and beverage flavoring, DESU contributes mild fruity and wine-like notes at low concentrations, functioning as a flavorant by interacting with olfactory receptors. In personal care formulations, it acts as an emollient and solvent carrier, improving spreadability and solubilizing active ingredients. Printing and packaging applications use it as a low-volatility solvent to control ink viscosity and drying profiles.
Diethyl succinate is available in food-grade quality meeting FCC specifications and in technical grade for industrial applications. It is fully registered under REACH and classified under HS code 29171990. Standard packaging includes drums and IBC containers, with documentation available to support food and cosmetic compliance requirements.
