Used as an intermediate in the synthesis of important chemical compounds in the pharmaceutical industry, particularly in the production of biologically active substances such as antimicrobial or anti-inflammatory drugs. The structure featuring both bromine and chlorine groups enables various subsequent reactions, such as nucleophilic substitution or carbon-carbon bond formation via copper- or palladium-catalyzed reactions, making it suitable for creating complex derivatives in pharmaceutical research and development laboratories. Additionally, it is used in research on organic electronic materials, as the cyclic structure containing sulfur can be developed into organic conductive materials.
