Used in pharmaceutical research as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly for targeted cancer therapies. Exhibits strong inhibitory activity against specific receptor tyrosine kinases involved in tumor growth and angiogenesis. Its structure enables selective binding and improved metabolic stability, making it valuable in developing anticancer agents with enhanced potency and reduced off-target effects. Also investigated for use in PET imaging probes due to fluorine content, allowing for non-invasive tracking in biological systems.
