Used as a versatile alkylating agent in organic synthesis, particularly in the preparation of cyclic compounds through intramolecular reactions. Its diiodo functionality allows for sequential substitution reactions, making it valuable in the construction of heterocycles and macrocycles. Commonly employed in the synthesis of pharmaceutical intermediates and functionalized polymers. The copper chip stabilization prevents decomposition, ensuring reactivity and shelf life during storage and use. Also utilized in materials science for modifying surfaces and creating molecular linkers in supramolecular architectures.
