Synthesis and photochromism studies of 1-(2-methyl-3-benzothiophene)-2-[2-methyl-5-(4-aminomethanephenyl)-3-thienyl]perfluorocyclopentene was written by Dong, Xiaorong;Wei, Shasha;Liu, Gang;Pu, Shouzhi. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2014.HPLC of Formula: 10243-15-9 This article mentions the following:
A new unsym. photochromic diarylethene compound, 1-(2-methyl-3-benzothiophene)-2-[2-methyl-5-(4-aminomethanephenyl)]-3-thienyperfluorocyclopentene (I) was synthesized and its photochromic properties were examined The result indicated that the compound I changed the color from colorless to purple upon irradiation with 297 nm UV light, in which absorption maxima was observed at 564 nm in acetonitrile. The kinetic experiments showed that the cyclization and cycloreversion processes were zeroth and first order reactions, resp. This new photochromic system also exhibited fluorescence switching in acetonitrile solution In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9HPLC of Formula: 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) 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: 10243-15-9
