Tert-butyloxycarbonyl (t-boc) aliphatic iodide is a common functional group used in drug research and development. It belongs to the class of alkylating agents and is used as a reagent for the introduction of iodine into organic compounds. The t-boc group is a protecting group used to temporarily mask the amine functionality in organic synthesis. The resulting t-boc-protected amine can be selectively deprotected at a later stage in the synthesis to reveal the free amine. This method is widely used in the production of pharmaceuticals, agrochemicals, and materials science.
