Used extensively in the pharmaceutical industry to improve the solubility and stability of poorly water-soluble drugs. It enhances drug delivery by forming inclusion complexes, which can increase bioavailability and control release rates. Also applied in analytical chemistry as a chiral selector in capillary electrophoresis for separating enantiomers. Its sulfobutyl groups provide strong ionic interactions, making it effective in various separation techniques. Additionally, it is utilized in environmental science for the removal of organic pollutants from water through complexation. Its versatility and effectiveness make it a valuable tool in drug formulation, analytical methods, and environmental remediation.
