Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of kinase inhibitors and other targeted therapies. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in research settings to design new drug candidates, especially in oncology and inflammation-related treatments. Also utilized in the preparation of fluorescent dyes and optical materials due to its conjugated pyrrole core.
