Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating active compounds that target specific signaling pathways in tumor cells. Commonly employed in research and development of anticancer agents due to its reactivity and ability to form stable derivatives. Also utilized in the preparation of tyrosine kinase inhibitors, which play a role in regulating cell growth and proliferation.
