4,7-Dibromo-2,1,3-benzothiadiazole, 97%

Description

CAS: 15155-41-6 | C6H2Br2N2S | 293.96 g/mol

4,7-Dibromo-2,1,3-benzothiadiazole is the building block or monomer for the synthesis of light-emitting diodes and conducting polymers for organic electronics. It is used as an intermediate for the synthesis of poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT) and poly[2,1,3-benzothiadiazole-4,7-diyl[4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene-2,6-diyl]] (PCPDTBT).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
4,7-Dibromo-2,1,3-benzothiadiazole is the building block or monomer for the synthesis of light-emitting diodes and conducting polymers for organic electronics.
