Used as an intermediate in organic synthesis, particularly in the preparation of functionalized anthraquinone derivatives which have applications in dyes and pigments. It serves as a building block in the development of electroactive materials and is employed in the synthesis of certain organic semiconductors. Its aldehyde group allows for easy modification via condensation or reduction reactions, making it valuable in pharmaceutical research for constructing complex polycyclic structures. Also utilized in the production of fluorescent compounds and sensors due to its conjugated aromatic framework.
