Used in the synthesis of pharmaceutical compounds, particularly in the development of molecules with potential therapeutic effects. It serves as a key intermediate in the creation of drugs targeting neurological disorders, such as epilepsy and anxiety, due to its structural compatibility with bioactive thienopyridine derivatives. Additionally, it is employed in organic chemistry research for constructing complex heterocyclic frameworks, which are essential in medicinal chemistry and drug discovery. Its chlorinated thienopyridine core makes it valuable for designing compounds with enhanced biological activity and selectivity.
