Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antithyroid agents. It serves as a building block in organic reactions where the thioamide group can be modified to form heterocyclic structures. Also employed in the preparation of agrochemicals and bioactive molecules due to its ability to participate in cyclization and condensation reactions. Its chlorophenyl moiety contributes to enhanced lipophilicity, making it useful in designing molecules with improved membrane permeability.
