Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anti-cancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in the preparation of benzoxazole and quinazoline derivatives, which exhibit biological activity such as anti-inflammatory and antimicrobial effects. Also utilized in research settings for designing enzyme inhibitors due to its ability to interact with active sites through hydrogen bonding and aromatic interactions.
