Claim: Most of the reactivity of thioacetic acid arises from the conjugate base thioacetate (an organosulfur compound with the molecular formula CH3COSH), wherein salts of this anion are used to generate thioacetate esters, which then undergo hydrolysis to give thiols.
Evidence: Potassium thioacetate is an organosulfur compound and a salt with the formula CH3COSK. The conjugate base is thioacetate: CH3COSH → CH3COS + H In neutral water, thioacetic acid is fully ionized. Thioacetic acid is an organosulfur compound with the molecular formula CH3COSH.
