Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.HPLC of Formula: 55219-11-9

A highly efficient one-pot reaction of 2-(gem-dibromovinyl)phenols(thiophenols) with K4Fe(CN)6 to 2-cyanobenzofurans(thiophenes) was written by Zhou, Wei;Chen, Wei;Wang, Lei. And the article was included in Organic & Biomolecular Chemistry in 2012.HPLC of Formula: 55219-11-9 This article mentions the following:

2-Cyanobenzofurans and 2-cyanobenzothiophenes I [R = H, 5-Me, 5-tBu, etc.; X = O, S] were prepared through an efficient one-pot Ullmann-reaction/cyanation reaction. In the presence of CuI/Na2CO3-Pd(OAc)2/PPh3 in DMF, the reaction of 2-(gem-dibromovinyl)phenols and 2-(gem-dibromovinyl)thiophenols with K4Fe(CN)6, as nontoxic and user-friendly cyanating reagent, proceeded smoothly to generate the corresponding 2-cyanobenzofurans and 2-cyanobenzothiophenes in good yields. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9HPLC of Formula: 55219-11-9).
