Used as a key intermediate in organic synthesis, particularly in the preparation of cyclic compounds through intramolecular reactions. Its dual iodo functionality allows for efficient ring closure via nucleophilic substitution or metal-catalyzed coupling reactions. Commonly employed in the synthesis of heterocycles and macrocycles, it serves as a versatile spacer in constructing molecular architectures for pharmaceuticals and functional materials. Also utilized in the development of specialty polymers and as a building block in coordination chemistry for designing ligands and metal-organic frameworks.
