Tandem absorbance and fluorescence detection following liquid chromatography for the profiling of multiclass phenolic compounds in different winemaking products was written by Ferreyra, Susana;Bottini, Ruben;Fontana, Ariel. And the article was included in Food Chemistry in 2021.HPLC of Formula: 10083-24-6 This article mentions the following:
A liquid chromatog. method coupling diode-array and fluorescence detectors (DAD and FLD, resp.) has been developed for the simultaneous quantification of 32 phenolic compounds (PCs) in winemaking products. With the combination of both detectors it was possible to determine phenolic acids, flavanols, flavonols, stilbenes and other PCs in the matrixes under study. An excitation wavelength of 290 nm was selected and three different emission wavelengths (315, 360 and 400 nm) were recorded. The method provided detection and quantification limits (LODs and LOQs) within the ranges of 0.01-1.46 mg/L and 0.03-4.9 mg/L, resp. The LODs and LOQs using FLD for flavanols, stilbenes and Ph ethanol analogs were improved between 65 and 1000% as compared with DAD. The combination of DAD with FLD increased both, sensitivity and the ability to reduce interfering signals. The developed method was applied for the characterization of PCs of wines, bunch stems and grape canes. In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6HPLC of Formula: 10083-24-6).
(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.HPLC of Formula: 10083-24-6
