Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Acts as a building block in the development of plant growth regulators, particularly in the synthesis of naphthalene-based auxins. Its chlorinated naphthyl structure enhances reactivity and binding affinity in biological systems. Employed in research for developing novel compounds with hormone-like activity in plants. Also explored in the design of specialty chemicals requiring aromatic thioether functionality for improved stability and lipophilicity.
