Used as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly in the development of anticancer agents. Its structure enables selective binding to enzyme active sites, making it valuable in pharmaceutical research for targeted therapies. Commonly employed in the preparation of small-molecule drugs aimed at treating cancers such as chronic myeloid leukemia and non-small cell lung carcinoma. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
