Used as a crosslinking agent in the production of hydrogels for biomedical applications such as contact lenses, drug delivery systems, and tissue engineering scaffolds. Its ability to form stable, water-swollen networks makes it ideal for controlled release formulations and soft biomaterials. Also employed in dental composites and coatings due to its polymerization characteristics and biocompatibility. Commonly used in photopolymerizable systems where rapid curing under UV or visible light is required.
