Cyclohexylthiophthalimide

Cyclohexylthiophthalimide (abbreviated CTP) is an organosulfur compound that is used in production of rubber. It is a white solid, although commercial samples often appear yellow. It features the sulfenamide functional group, being a derivative of phthalimide and cyclohexanethiol.[1] In the production of synthetic rubber, CTP impedes the onset of sulfur vulcanization.
