5-Bromobenzofuran-2-carboxylic acid (cas: 10242-11-2) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.COA of Formula: C9H5BrO3

Decarboxylative Fluorination of Electron-Rich Heteroaromatic Carboxylic Acids with Selectfluor was written by Yuan, Xi;Yao, Jian-Fei;Tang, Zhen-Yu. And the article was included in Organic Letters in 2017.COA of Formula: C9H5BrO3 This article mentions the following:

A transition-metal-free decarboxylative fluorination of electron-rich five-membered heteroaromatics, including furan-, pyrazole-, isoxazole-, thiophene-, indole-, benzofuran- and indazolecarboxylic acids, with Selectfluor is reported. Fluorinated dimer products were observed for nitrogen-containing heteroaromatic carboxylic acids, such as indole and pyrazole. An effective method has been developed to synthesize the monomer of 2- and 3-fluoroindoles with Li2CO3 as base at low temperature In the experiment, the researchers used many compounds, for example, 5-Bromobenzofuran-2-carboxylic acid (cas: 10242-11-2COA of Formula: C9H5BrO3).
