Used as a key intermediate in the synthesis of sunitinib, a multi-targeted receptor tyrosine kinase inhibitor. It plays a critical role in the development of anticancer drugs, particularly for the treatment of renal cell carcinoma and gastrointestinal stromal tumors. The compound contributes to the structural framework that enables selective inhibition of tyrosine kinases involved in tumor growth and angiogenesis. Its application is primarily in pharmaceutical research and development for oncology therapeutics.
