1,3,6,8-Pyrenetetrasulfonic acid tetrasodium salt (CAS 59572-10-0)

1,3,6,8-Pyrenetetrasulfonic acid tetrasodium salt (CAS: 59572-10-0) is a highly water-soluble derivative of pyrene, a polycyclic aromatic hydrocarbon well-regarded for its vivid photophysical properties. This compound incorporates four sulfonic acid groups, each converted into its sodium salt form, which dramatically enhances its solubility in aqueous solutions compared to its non-sulfonated pyrene counterpart. The introduction of sulfonic acid groups on the pyrene core not only increases water compatibility but also adds ionic character, making it ideal for various analytical applications in hydrophilic environments. The primary action mechanism of this compound centers around its strong fluorescence emission when excited by ultraviolet light. The fluorescence properties of 1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt make it exceptionally useful as a fluorescent tracer or probe in environmental science, particularly for studying the behavior and fate of polycyclic aromatic hydrocarbons in water bodies. This compound has been extensively utilized in research to explore the dynamics of water-soluble pollutants, where its ability to fluoresce enables precise tracking and quantification. Additionally, its high fluorescence quantum yield and stability under physiological conditions have found applications in the study of biological systems, where it facilitates investigations into cell dynamics and interactions without the need for invasive techniques.
