4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.HPLC of Formula: 38183-12-9

Determination of sulfonamides in feeds by high-performance liquid chromatography after fluorescamine precolumn derivatization was written by Patyra, Ewelina;Przenioslo-Siwczynska, Monika;Kwiatek, Krzysztof. And the article was included in Molecules in 2019.HPLC of Formula: 38183-12-9 This article mentions the following:

A new multi-residue method for the anal. of sulfonamides (sulfadiazine, sulfamerazine, sulfamethazine, sulfaguanidine and sulfamethoxazole) in non-target feeds using high-performance liquid chromatog.-fluorescence detection (HPLC-FLD) and precolumnderivatization was developed and validated. Sulfonamides (SAs) were extracted from feed with an Et acetate/methanol/acetonitrile mixture Clean-up was performed on a Strata-SCX cartridge. The HPLC separation was performed on a Zorbax Eclipse XDB C18 column with a gradient mobile phase system of acetic acid, methanol, and acetonitrile. The method was validated according to EU requirements (Commission Decision 2002/657/EC). Linearity, decision limit, detection capability, detection and quantification limits, recovery, precision, and selectivity were determined, and adequate results were obtained. Using the HPLC-FLD method, recoveries were satisfactory (79.3-114.0%), with repeatability and reproducibility in the range of 2.7-9.1% to 5.9-14.9%, resp. Decision limit (CCα) and detection capability (CCβ) were 197.7-274.6 and 263.2-337.9 μg/kg, resp., and limit of detection (LOD) and limit of quantification (LOQ) were 34.5-79.5 and 41.3-89.9 μg/kg, resp., depending on the analyte. Results showed that this anal. procedure is simple, rapid, sensitive, and suitable for the routine control of feeds. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9HPLC of Formula: 38183-12-9).
