Gas chromatographic analysis of benzofuran derivatives was written by Nakanishi, Teruo;Ito, Kiyoshi. And the article was included in Nippon Nogei Kagaku Kaishi in 1969.COA of Formula: C10H8O3 This article mentions the following:
Retention times (tr in min) of 53 benzofuran derivatives are given for 3 stationary phases at 140-300°. The columns were: (1) 5% diethylene glycol adipate on Chromosorb W, 3 mm inner diameter × 1.11 m; (2) 20% Apiezon grease L on Neosorb NC, 3 mm inner diameter × 1.11 m; (3) 10% Silicone SE-30 on Chromosorb W, 3 mm inner diameter × 0.74 m. A H flame ionization detector was used in each case. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1COA of Formula: C10H8O3).
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. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.COA of Formula: C10H8O3
