CAS:Acid Red 18 is an acid dye that is used as an analytical method for cellulose. It has been shown to be effective in the treatment of wastewater and infectious diseases, such as cholera and typhoid fever. Acid Red 18 is a long-term toxicant and can induce allergic symptoms at high concentrations. The optimum concentration for adsorption varies from one material to another but ranges from 0.1% to 1%. Synchronous fluorescence spectroscopy is a technique used to measure the adsorption of dye on a surface, which can be useful in nuclear DNA analysis.Formula:C20H11N2Na3O10S3Purity:Min. 95%Color and Shape:Red SolidMolecular weight:604.48 g/molRef: 3D-FA41143
