S-Ethyl thioacetate is the organosulfur compound with the formula CH₃C(O)SC₂H₅. It is an ethyl ester of thioacetic acid. The compound is traditionally prepared by alkylation of potassium thioacetate and thiolation of acetyl chloride:^[1]

CH₃COSK + C₂H₅Br → CH₃C(O)SC₂H₅ + KBr

CH₃COCl + C₂H₅SH → CH₃C(O)SC₂H₅ + HCl

The compound has been well studied in part as a model for biologically relevant thioesters, such as Coenzyme A. H-D exchange of the methyl group has been examined in aqueous solution.^[2]
