Used as a chain transfer agent in polymer chemistry, particularly in free radical polymerizations. It helps control molecular weight and dispersity of polymers by regulating chain growth. Its steric bulk from the isopropyl groups enhances selectivity and efficiency in sulfur-based transfer reactions. Also employed in the synthesis of functionalized polymers and block copolymers where precise molecular architecture is required. Additionally, serves as an intermediate in organic synthesis for introducing thiol functionality in sterically hindered environments.
