Description
Diethyl carbonate (CAS 105-58-8) is a carbonate ester solvent commercially known under trade names including H-DEC, Eufin, and Diatol. It carries no assigned E-code and is catalogued under HS code 2920 90 10. The compound is registered under REACH and recognised in both food-grade and pharmaceutical-grade specifications.
In pharmaceutical manufacturing, diethyl carbonate functions as a reaction solvent and carbonylating agent, facilitating carbonate bond formation under mild conditions. In food and beverage processing, it acts as an antimicrobial preservative by disrupting microbial enzyme activity, and it is also approved as a flavorant in certain regulated applications.
Diethyl carbonate is available in technical, food-grade (FCC-compliant), and pharmaceutical-grade (Ph.Eur.-aligned) specifications. Packaging typically includes drums and IBC containers suited to industrial procurement volumes. Buyers should confirm current REACH registration status and applicable food-contact or GMP documentation requirements with the supplier prior to ordering.
