4-Bromo-2-iodophenol (cas: 207115-22-8) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.COA of Formula: C6H4BrIO

A General Approach to Optically Pure [5]-, [6]-, and [7]Heterohelicenes was written by Zadny, Jaroslav;Jancarik, Andrej;Andronova, Angelina;Samal, Michal;Vacek Chocholousova, Jana;Vacek, Jaroslav;Pohl, Radek;Saman, David;Cisarova, Ivana;Stara, Irena G.;Stary, Ivo. And the article was included in Angewandte Chemie, International Edition in 2012.COA of Formula: C6H4BrIO This article mentions the following:

A general method for the preparation of optically pure [5]-, [6]-, and [7]heterohelicenes is based on a CoI– or Ni0-catalyzed diastereoselective [2+2+2] cycloisomerization of centrally chiral triynes to deliver helicenes containing two 2H-pyran rings. The configuration, which can be predicted, does not depend on helicene length or functional groups present. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-iodophenol (cas: 207115-22-8COA of Formula: C6H4BrIO).
