Used as an intermediate in the synthesis of dyes and pigments, particularly for producing naphthoic acid derivatives with optical and electronic properties. Plays a role in the development of fluorescent probes and labeling agents in biochemical applications due to its ability to form stable conjugates with amines. Also utilized in the preparation of liquid crystal materials and organic semiconductors, where the cyano and carboxylic functional groups contribute to molecular alignment and charge transport characteristics. Its rigid aromatic structure makes it suitable for research in supramolecular chemistry and sensor design.
