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 the preparation of biologically active compounds targeting tyrosine kinases, which play critical roles in signal transduction pathways involved in tumor growth and proliferation. Its structure allows for selective modification to enhance drug potency and bioavailability. Commonly employed in research and development of targeted therapies for oncology, especially in the design of small molecule inhibitors.
