Used primarily as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly in anticancer drug development. Its structure enables selective binding in signaling pathways involved in tumor growth, making it valuable in pharmaceutical research for targeted therapies. Commonly utilized in the preparation of small-molecule inhibitors for treating cancers such as chronic myeloid leukemia and non-small cell lung carcinoma. Also employed in medicinal chemistry for optimizing drug candidates due to its stability and reactivity in coupling reactions.
