Used as a reactive intermediate in organic synthesis, particularly in the production of crosslinking agents and functional polymers. Its hydroxyl and vinyl groups allow for dual reactivity, making it valuable in creating polymer networks for coatings, adhesives, and specialty resins. Commonly employed in the development of functionalized polystyrene derivatives and as a building block in the synthesis of liquid crystal materials. Also finds use in immobilizing molecules on surfaces for sensors and diagnostic devices due to its ability to undergo radical polymerization and covalent attachment.
