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 preparation of bioactive molecules due to its ability to form stable heterocyclic structures. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting central nervous system disorders and inflammatory diseases. Its reactivity allows for easy functionalization, making it valuable in combinatorial chemistry and high-throughput screening campaigns.
