4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Category: benzofurans

Simultaneous determination of 16 sulfonamide residues in beef by high performance liquid chromatography-fluorescence detection with online post-column derivatization was written by Xu, Xu;Xiao, Yuancan;Geng, Dandan;Pi, Li;Dong, Qi;Hu, Fengzu. And the article was included in Sepu in 2016.Category: benzofurans This article mentions the following:

In this study, we investigated the effects of the four kinds of derivatization reagents, including fluorescamine, o-phthaladehyde, fluorescein isothiocyanate isomer and 2,3-naphthalenedicarboxaldehyde. A high performance liquid chromatog. with fluorescence detection method for the rapid determination of 16 sulfonamide residues in beef was developed by using improved QuEChERS method for sample pretreatment and fluorescamine for online post-column derivatization. The beef samples were extracted with acetonitrile containing 1% (volume/volume) acetic acid, cleaned-up by QuEChERS method, injected for online post-column derivatization with fluorescamine, and then analyzed with fluorescence detection. Under the optimized conditions of QuEChERS and chromatog., the 16 sulfonamide residues showed good linearities in the range of 0.024-2.533 mg/L with the correlation coefficients (γ) higher than 0.992. The limits of detection of the method were 1.6 to 8.2 μg/kg. The average recoveries of the 16 sulfonamide residues were in the range of 66.6%-109.5% with the relative standard deviations from 0.9% to 9.9%. The method has the advantages of rapidity, simplicity, high sensitivity and better purification effect. It is suitable for the rapid determination of the sulfonamide residues in beef. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9Category: benzofurans).
