Butyl isocyanate is an intermediate of the germicide benomyl. Butyl isocyanate is typical catalyst for the synthesis of the sulfonylurea herbicides, such as chlorsulfuron, sulfometuron, metsulfuron-methyl, and chlorimuron-ethyl, by treating the different groups substituted sulfonamide with phosgene in the presence of butyl isocyanate. Moreover, butyl isocyanate is also an intermedia for the synthesis of sulfonylurea.A number of novel sulfonylurea derivatives with sugar lowering activity, such as glibenclamide, tolbutamide, chlorpropamide and other hypoglycemic sulfonylurea agents also could be synthesized by using butyl isocyanate as synthetic intermediate.
