Used as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly in the development of anticancer agents. It plays a role in targeting signaling pathways involved in tumor growth and progression, especially in compounds designed to inhibit epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK). Its structure supports high binding affinity to mutant forms of these kinases, making it valuable in creating targeted therapies for non-small cell lung cancer and other malignancies. Also utilized in research settings to develop new pharmaceuticals with improved selectivity and reduced resistance profiles.
