Used as a reducing agent in organic synthesis, particularly in dehalogenation and deoxygenation reactions. It plays a key role in the preparation of sulfoxides and sulfones through controlled oxidation processes. Commonly employed in pharmaceutical manufacturing for the synthesis of sulfur-containing active ingredients. Also utilized in polymer chemistry as a chain transfer agent or initiator in radical polymerization. Its ability to generate sulfur-centered radicals makes it valuable in materials science and specialty chemical production.
