Used as a reactive monomer in polymer synthesis, particularly in the production of specialty resins and copolymers with improved stability and solubility. Acts as a protecting group in organic synthesis due to its ability to form acid-labile derivatives, useful in multi-step reactions involving alcohols or acids. Employed in the formulation of coatings, adhesives, and sealants where controlled reactivity and volatility are required. Also serves as an intermediate in the manufacture of pharmaceuticals and agrochemicals.
