Used in polymer chemistry as a monomer for producing functional polystyrene derivatives with enhanced thermal and oxidative stability. Its methoxy group allows for further chemical modifications, making it valuable in synthesizing specialty resins, optical materials, and liquid crystals. Also employed in the development of sensors and separation materials due to its ability to participate in charge-transfer interactions. Commonly applied in research for creating stimuli-responsive polymers and in the pharmaceutical industry as an intermediate in drug synthesis pathways.
