Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective binding and modification in drug design, making it valuable in medicinal chemistry research. Commonly employed in reactions where cyano and chloro functional groups undergo transformations to form more complex heterocyclic systems. Also utilized in the preparation of fluorescent probes due to its ability to participate in conjugation reactions that enhance photostability and emission properties.
