2-(Propylamino)ethanol is primarily used as an intermediate in the synthesis of various chemical compounds, particularly in the production of surfactants and emulsifiers. These surfactants are widely applied in the formulation of personal care products, such as shampoos, conditioners, and skin cleansers, where they help to improve the texture and stability of the products. Additionally, it is utilized in the manufacture of industrial cleaning agents, where its properties aid in breaking down grease and dirt effectively. In the pharmaceutical industry, it serves as a building block for the synthesis of active pharmaceutical ingredients (APIs) and other drug-related compounds. Its versatility also extends to its use in corrosion inhibitors, which are essential in protecting metal surfaces in various industrial applications.
