Description
- General description: Fluorescein sodium salt (uranine) is a xanthene dye, which finds applications as a fluorescent tracer and shows the best of fluorescence in the pH range 6 to 11.[1] Uranine is also employed as a coloring additive in drugs and cosmetics. It is known to exhibit optical chemical sensing and fluorescent properties in biological staining procedures.[2]
- Application: Fluorescein sodium salt is used as an analytical standard in determining the formation of hydroxy radicals, by the ZnO-based photocatalysts under UV-filtered simulated sunlight using spectrofluorometry.[3] It is also used as a calibration standard for the label-free measurements of metabolic events within cells in the living animals using fluorescence lifetime imaging microscopy (FLIM).[4]It may also be used as an analytical reference standard for the quantification of the analyte in the following:Soil samples using high-performance liquid chromatography (HPLC).[2]Coffee samples using high-performance liquid chromatography (HPLC) and capillary electrophoresis (CZE).[5]
- Analysis Note: remarks on ICP: Na positive
