Diethyl succinate

Diethyl succinate (CAS 123-25-1 ), also known by its FEMA 2377 designation, is a mild-odor ester used as a solvent, carrier, and flavoring agent across food, cosmetic, and industrial applications.

Its low volatility and compatibility with a broad range of active ingredients make it a practical choice for formulators managing solubility and delivery challenges in various chemical processes.

In food and beverage manufacturing, it functions as a flavor modifier with a faint fruity, wine-like note, used in small concentrations to round out flavor profiles in confectionery and alcoholic beverages.

Cosmetic and personal care formulators use it as a carrier solvent and humectant in skin creams, lotions, and fragrance blends where a non-greasy, slow-evaporating base is required for the product.

In printing inks and coatings, it acts as a coalescing solvent that supports film formation and pigment dispersion on flexible packaging substrates. It also serves as a reaction solvent and intermediate.

This material is utilized in specialty chemical synthesis where a high-boiling, relatively inert ester medium is needed. Diethyl succinate is supplied as a clear, colorless liquid in drum and IBC quantities.

Food-grade material conforming to FEMA standards is the most commonly traded specification, with technical-grade available for industrial solvent applications. Purity typically ranges from 99% upward.

This high purity level is essential for flavor and cosmetic end uses, ensuring consistent performance and safety across all manufacturing sectors and specialized chemical applications.
