Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form hydrogen bonds and interact with biological targets. Commonly employed in the preparation of small-molecule drugs targeting inflammatory diseases and certain types of tumors. Its structure allows for easy modification, making it valuable in structure-activity relationship (SAR) studies during drug discovery. Also utilized in the production of protease inhibitors and in research related to central nervous system disorders.
