Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cyclin-dependent kinases (CDKs). It plays a role in the development of potential anticancer agents due to its ability to interfere with cell cycle regulation. Also investigated for use in treatments involving neurodegenerative diseases and viral infections, owing to its structural properties that support binding to specific enzyme active sites. Its derivatives are explored for improved selectivity and potency in drug candidates.
