Methyl-β-cyclodextrin is widely used in pharmaceutical research for its ability to enhance the solubility and stability of poorly water-soluble drugs. It acts as a drug delivery agent by forming inclusion complexes with hydrophobic molecules, improving their bioavailability and absorption in the body. In cell biology, it is employed to manipulate cholesterol levels in cell membranes, aiding in the study of lipid rafts and membrane dynamics. Additionally, it is utilized in the food and cosmetics industries as an emulsifier and stabilizer, improving the texture and shelf life of products. Its unique structure also makes it valuable in environmental applications for the removal of organic pollutants from water.
