Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) targeting tyrosine kinase receptors, which play a role in tumor growth and progression. Its halogen substitution pattern allows for selective cross-coupling reactions, enabling the introduction of various functional groups during drug design. Commonly employed in research and development of antitumor, antiviral, and anti-inflammatory agents.
