However, saccharin and its derivatives offer other opportunities and challenges to the synthetic chemists and biologist for the appropriate use of the same in different way, and we believe that these opportunities will never end because these catalysts will indeed form a huge source for catalytic strategies. Although saccharin was commercialized not long after its discovery, until sugar shortages during World War I, its use had not become widespread. Fortunately, molecules with similar functional groups tend to undergo similar reactions. It is also used as a precursor to various materials, including plastics, resins, and other polymers. Oxidation of the methyl substituent gives the carboxylic acid, which cyclicizes to give saccharin free acid:[41], In 1950, an improved synthesis was developed at the Maumee Chemical Company of Toledo, Ohio.
