Used as an intermediate in the synthesis of functional organic materials, particularly in the development of naphthalene-based dyes and pigments due to its conjugated structure and ability to undergo further chemical modifications. Its cyano and hydroxyl groups allow for coordination with metal ions, making it useful in the design of metal-organic frameworks (MOFs) and sensors. Also employed in the preparation of electroactive compounds for organic semiconductors and optoelectronic devices. Its rigid aromatic backbone supports applications in photophysical studies and as a building block in supramolecular chemistry.
