Used as an intermediate in the synthesis of liquid crystal monomers, particularly in the production of side-chain liquid crystalline polymers. Its aldehyde functional group allows for further chemical modifications, such as condensation reactions to form imines or reduction to alcohols, enabling tailored molecular design. Commonly employed in the development of electro-optic materials and advanced organic materials where precise molecular alignment is required. Also utilized in pharmaceutical research as a building block for bioactive compounds due to its flexible spacer and reactive functional groups.
