Thioacetic acid is the thioester of acetic acid and features a sulfur atom bonded to an acetyl group (-COSH). Thioacetic acid is highly reactive and unstable, decomposing rapidly in air. It is primarily used as a chemical reagent in organic synthesis to introduce thioester functionalities into molecules. Due to its strong odor and hazardous nature, thioacetic acid requires careful handling and storage under controlled conditions to prevent accidents and exposure.
