Used as an intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It plays a key role in the preparation of compounds targeting tyrosine kinases, which are involved in signal transduction pathways associated with tumor growth and proliferation. Its structure allows for selective modification to enhance binding affinity and pharmacokinetic properties in drug candidates. Commonly utilized in medicinal chemistry research for generating libraries of bioactive molecules aimed at treating various cancers, including lung and breast cancer.
