Used primarily as an intermediate in the synthesis of pharmaceuticals and biologically active compounds. Its brominated structure allows for further functionalization through cross-coupling reactions, making it valuable in drug development and medicinal chemistry research. Commonly employed in the preparation of kinase inhibitors and other targeted therapies. Also utilized in the creation of fluorescent probes and imaging agents due to its stable heterocyclic core. Suitable for use in solid-phase synthesis and combinatorial chemistry for generating compound libraries.
