Used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals and agrochemicals. It serves as a building block in the synthesis of complex molecules, particularly in the development of compounds with potential biological activity. Its aldehyde group allows for further functionalization through reactions like condensation, oxidation, or reduction, making it versatile in chemical transformations. Additionally, it is employed in the production of liquid crystals and organic electronic materials due to its biphenyl structure, which contributes to desirable electronic and optical properties.
