What is Diethyl Succinate?

Diethyl Succinate is the diethyl ester of succinic acid. It is a clear, mobile liquid characterized by its mild, pleasant, fruity aroma, which makes it valuable in flavor and fragrance applications. It is produced by the esterification of succinic acid with ethanol. The compound exhibits good solvating power for many resins and polymers, moderate volatility, and excellent stability. It is a versatile chemical intermediate and a benign, "green" solvent due to its low toxicity and favorable environmental profile.

Application:

1. Flavor and Fragrance: Widely used as a flavoring agent in food (e.g., confectionery, beverages) for its fruity, wine-like notes and as a fragrance ingredient in perfumes and cosmetics for its mild, diffusive character.

2. Chemical Intermediate: Serves as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and other fine chemicals.

3. Solvent: Used as a high-boiling, polar aprotic solvent for resins (e.g., cellulose acetate, acrylics), inks, and coatings. It is considered an eco-friendly solvent.

4. Plasticizer: Acts as a plasticizer for cellulose esters and other polymers, though its volatility limits its use in long-life products.

5. Perfumery Base: Used as a base and fixative in perfumery compositions.

Safety profile:

Diethyl Succinate is generally recognized as safe (GRAS) for use as a flavoring agent by the FDA and FEMA. It has low acute toxicity, is non-irritating to skin under normal conditions, and is readily biodegradable. It is considered a non-hazardous substance. Good industrial hygiene practices should be followed. Use gloves and safety glasses to prevent prolonged contact.

Storage requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and ignition sources. Keep containers tightly closed to prevent moisture absorption and evaporation. Recommended storage temperature: 10-40 °C. Store away from strong oxidizing agents, strong acids, and strong bases.

Transport & Packaging:

Diethyl Succinate is typically supplied in 25 kg and 200 kg HDPE drums or stainless steel containers. Classified as non-hazardous for transport.
