And the article was included in Angewandte Chemie, International Edition in 2022.Safety of 5-Fluoro-1-benzothiophene-2-carboxylic acid This article mentions the following:
A practical synthesis of nonsym. thiophene-fused aromatic systems has been developed that was inspired by the biodegradation of benzothiophene. For the first time, the photophys. properties of a series of π-conjugated benzo[b]naphtho[1,2-d]thiophene (BNT) sulfoxides, I [R = H, Br, MeO, 4-FC6H4, R1 = H, Br, Me, MeO, R2 = Br, Cl, CN, etc., R3 = H, Br, MeO, Ph, 3-O2NC6H4, 4-MeOC6H4, 4-FC6H4, R4 = H, Br, MeO, Ph, 3-O2NC6H4, 4-MeOC6H4, 4-FC6H4, R5 = Br, Cl, 2-methoxy-3-pyridinyl, etc., R6 = H, Br, Me, R7 = H, Br, MeO, 4-FC6H4], were explored both in solution and in the solid state. The excellent fluorescence characteristics enable various applications of these compounds In the experiment, the researchers used many compounds, for example, 5-Fluoro-1-benzothiophene-2-carboxylic acid (cas: 70060-13-8Safety of 5-Fluoro-1-benzothiophene-2-carboxylic acid).
5-Fluoro-1-benzothiophene-2-carboxylic acid (cas: 70060-13-8) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Safety of 5-Fluoro-1-benzothiophene-2-carboxylic acid
