Used as an intermediate in the synthesis of high-performance polymers, particularly polyethersulfones and polysulfides, which exhibit excellent thermal stability, chemical resistance, and mechanical strength. Commonly employed in aerospace, automotive, and electronic industries for manufacturing durable components and membranes. Also utilized in the production of specialty chemicals and agrochemicals due to its reactive chlorine groups that allow further functionalization. Shows utility in research for developing new sulfur-containing organic compounds with potential biological activity.
