Used primarily as a crosslinking agent in polymer chemistry, this compound enables the formation of highly stable three-dimensional networks in resins and thermosetting materials. Its dual bromomethyl groups readily react with nucleophiles, making it valuable in modifying polymers for enhanced thermal and mechanical properties. It is also employed in the synthesis of functional monomers for specialty coatings and in the development of porous organic frameworks for gas storage or catalysis. Additionally, it serves as a building block in the preparation of dendrimers and other branched macromolecular structures.
