Used primarily as an alkylating agent in organic synthesis, it facilitates the introduction of the 2-methylbutyl group into various molecules. It is particularly valuable in the preparation of complex organic compounds, including pharmaceuticals and agrochemicals. The stabilization with copper chips prevents the formation of iodine, ensuring the reagent's stability and effectiveness during reactions. It is also employed in nucleophilic substitution reactions, where it acts as a source of the 2-methylbutyl cation. Additionally, it finds use in research and development laboratories for exploring new chemical reactions and pathways.
