Color reaction of 3-methyl-2-thiohydantoin (MTH) in alkaline solution was investigated by polarographic method. Hydrogen peroxide and bis (3-methyl-2-thiohydan-toinylidene-5) were confirmed in the autoxidation products of MTH and their apparent ratio was determined by this method. Effect of metal ions on the autoxidation of MTH was also studied and a reaction mechanism was proposed.
