Infrared spectra of some substituted benzofuran derivatives was written by Epstein, W. W.;Horton, W. J.;Lin, C. T.. And the article was included in Journal of Organic Chemistry in 1965.Recommanded Product: 1646-27-1 This article mentions the following:
The ir spectra of a number of simple and complex substituted benzofurans (I) were studied. The findings indicated a relationship between the presence or absence of furan H atoms and medium to strong bands in the 1020-1180-cm.-1 region. I were divided into 2 groups. One group wherein R1 = H and the 2nd group in which R1 = COMe, CO2Me, CO2H, iso-Pr, iso-PrCO, C:CHMe, and COCH2COMe. The 1st had 2 bands, one in the 1125-1160cm.-1 region and the other in the 1029-1087-cm.-1 region associated with the in-plane bending modes of the β- and α-H atoms on the furan nucleus. The 2nd had only 1 band at 1121-1172 cm.-1 characteristic of the β-H. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1Recommanded Product: 1646-27-1).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Recommanded Product: 1646-27-1
