Low price, high-purity BT-HD-2Br available to buy online

Bithiophene derivative with bulky branched side chains


BT-HD-2Br (5,5’-Dibromo-4,4’-bis(2-hexyldecyl)-2,2’-bithiophene) is a bithiophene derivative that has bulky branched side chains to promote both solubility and crystallinity of the targeting compounds. With bromine on the both ends, BT-HD-2Br can engage either Stille or Suzuki coupling reaction for oligomer or polymer synthesis.

We supply high purity BT-HD-2Br as part of our range of thiophene, TT, BDT, BDD, FL and Cz containing monomers (alternatively, browse all monomers). Available in quantities of 1 g, 5 g, or 10 g with worldwide shipping and additional Discounts for large orders. Buy online or request a quote today.
