Used in the synthesis of pharmaceutical intermediates, particularly in the development of bioactive molecules and heterocyclic compounds. Its structure supports the construction of complex organic frameworks found in certain antitumor and antimicrobial agents. Commonly employed in cross-coupling reactions, such as Suzuki and Heck reactions, to form carbon-carbon bonds in medicinal chemistry research. Also serves as a building block in the preparation of functionalized benzothiazoles for use in material science and fluorescent dyes.
