Potassium thioacetate is an organosulfur compound and a salt with the formula CH₃COS⁻K⁺. This white, water-soluble solid is used as a reagent for preparing thioacetate esters and other derivatives.

Potassium thioacetate, which is commercially available, can be prepared by combining acetyl chloride and potassium hydrogen sulfide:

It arises also by the neutralization of thioacetic acid with potassium hydroxide.

In a common application, potassium thioacetate combines with alkylating agents to give thioacetate esters:

Hydrolysis of these esters affords thiols:
