Thioacetamide CAS 62-55-5 is a colorless or white crystal. The melting point is 113-114°C, the solubility in water at 25°C is 16.3g/100ml, and the ethanol is 26.4g/100ml. Very slightly soluble in benzene Chemicalbook, ether. Its aqueous solution is quite stable at room temperature or 50-60 ℃, but when there are hydrogen ions, it will quickly generate thiohydrogen and decompose. New products sometimes have mercaptan odor and slight moisture absorption.
