Octanol is a type of alcohol that is used as a solvent for various substances in research and industry. It is commonly used in the pharmaceutical and cosmetic industries for its ability to dissolve both polar and non-polar compounds. Octanol is also used in research to study the partitioning of chemicals between water and lipid phases, which is important for understanding the behavior of substances in biological systems. Additionally, octanol is used as a model system for studying membrane permeability and drug transport across cell membranes. Overall, research on octanol plays a crucial role in understanding the behavior of various substances in biological and industrial settings.
