Used as a key intermediate in organic synthesis, particularly in the preparation of cross-linking agents and radiopaque compounds. Its diiodo functionality allows for efficient coupling reactions in the development of pharmaceuticals and functional polymers. Commonly employed in the synthesis of dendrimers and polymeric networks due to its ability to introduce iodine-containing segments that enhance molecular weight and branching. Also utilized in the formulation of contrast agents for medical imaging, where iodine content provides necessary radiopacity. Its ether linkages contribute to solubility and flexibility in final products, making it suitable for specialty materials in both industrial and biomedical applications.
