N-Methyl-2-thiazolidinethione
N-Methyl-2-thiazolidinethione is the organosulfur compound with the formula C2H4S(NCH3)CS. It is classified as a heterocycle called a thiazolidine. It is a colorless or off-white solid. It has gained attention as a proposed low toxicity replacement for ethylenethioureas, which are used as accelerators for the vulcanization of chloroprene rubbers.[1] The compound is prepared by reaction of N-methylethanolamine and carbon disulfide.
