Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized polymers and specialty monomers. Its vinyl group enables participation in radical polymerization, allowing incorporation into polymer backbones for advanced materials. The tert-butyl carbonate moiety acts as a protected phenol, useful in multi-step synthesis where controlled deprotection is required. Commonly applied in the development of photoresists, optical materials, and pharmaceutical intermediates due to its stability and reactivity profile.
