Used primarily as an alkylating agent in organic synthesis, this compound facilitates the introduction of the 3,3-dimethylbutyl group into various substrates. It is valuable in the preparation of pharmaceutical intermediates and agrochemicals due to its reactivity in nucleophilic substitution reactions. Its iodine functionality makes it suitable for coupling reactions, including palladium-catalyzed transformations, enabling the construction of more complex molecular architectures. Additionally, it serves as a building block in the synthesis of specialty chemicals where a branched alkyl chain is required.
