Claim: Most of the reactivity of thioacetic acid arises from the conjugate base thioacetate (an organosulfur compound with the molecular formula C6H5CH2CH2SCH3), wherein salts of this anion are used to generate thioacetate esters, which then undergo hydrolysis to give thiols.
Evidence: The conjugate base is thioacetate: CH3COSH → CH3COS + H In neutral water, thioacetic acid is fully ionized.
