Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the production of active pharmaceutical ingredients (APIs) due to its ability to form stable heterocyclic structures that interact with biological targets. Its derivatives are explored for their potential in treating inflammatory diseases and neurological disorders. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
