Used primarily as a reactive monomer in polymer synthesis, enabling the introduction of hydroxymethyl groups into copolymers for enhanced crosslinking. Commonly applied in specialty resins and coatings where improved adhesion, thermal stability, and chemical resistance are required. Also serves as an intermediate in the production of ion-exchange resins and functional polymers for pharmaceutical and diagnostic applications. Its hydroxyl functionality allows further chemical modification, making it valuable in developing tailored polymeric materials for advanced industrial uses.
