2-(Butylamino)ethanol (CAS 111-75-1) is a multifunctional amino alcohol that combines amine and alcohol functionality in a clear, colorless to almost colorless liquid, supplied in Technical Grade as an intermediate for specialty surfactants and resins and as a neutralizing agent and stabilizer in water-borne coating systems. The molecule combines the properties of an amine and an alcohol, offering excellent solvency and reactivity for industrial chemical synthesis. It is highly valued for its ability to improve pigment dispersion and prevent corrosion in metallic coating applications. In industrial settings, it acts as a pH regulator and a catalyst in polyurethane production and textile chemical processing. Its low volatility compared to simpler amines provides a safer handling profile in high-temperature manufacturing environments.
