Used as a key intermediate in the synthesis of organic compounds, particularly for producing pharmaceuticals or bioactive substances featuring a benzo[b]thiophene structure. Especially in pharmaceutical research for developing drugs affecting the nervous system, antihypertensives, or anti-inflammatory agents. The structure with 3-chloro and 4-bromo substituents influences binding to biological targets, providing potential for modifying the properties of active substances. Its benzo[b]thiophene core supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for derivatization to enhance drug potency and selectivity. Additionally, used as a versatile intermediate in chemical reactions to create more complex derivatives in research laboratories. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and environmental profiles.
