The advancement of renewable energy technologies, particularly organic solar cells (OSCs) or organic photovoltaics (OPVs), relies heavily on the development of efficient and stable semiconducting materials. At the heart of many high-performance OPV polymers is the benzothiadiazole unit, and a key intermediate for its incorporation is 4,7-Dibromo-2,1,3-benzothiadiazole (CAS 15155-41-6). This compound acts as a critical monomer, enabling the synthesis of polymers with desirable electronic and optical properties essential for effective solar energy conversion.

As a leading supplier of fine chemicals, we are proud to provide researchers and manufacturers with high-purity 4,7-Dibromo-2,1,3-benzothiadiazole.
