Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It serves as a scaffold for targeting tyrosine kinases involved in tumor growth and angiogenesis. Its structure allows for easy modification to enhance binding affinity and selectivity toward specific enzyme targets. Also explored in the design of anti-inflammatory and neuroprotective compounds due to its ability to cross the blood-brain barrier in preclinical models.
