Product Description:

2-Aminoethanol, also known as monoethanolamine (MEA), is a primary amine and primary alcohol with the molecular formula C_H_NO. It is a viscous, hygroscopic liquid with a mild ammonia-like odor, produced by the reaction of ethylene oxide with ammonia. Its primary industrial application is as a versatile surfactant and chemical intermediate. In the category of daily and industrial chemicals, MEA is widely used as a surface-active agent in detergents, cleaning products, and personal care formulations, functioning as an emulsifier and pH adjuster. It is also a key component in gas treating processes for removing carbon dioxide and hydrogen sulfide. As a general synthetic building block, 2-aminoethanol serves as a fundamental reagent in organic synthesis, acting as a precursor for pharmaceuticals, agrochemicals, and corrosion inhibitors. Its dual functional groups (amine and hydroxyl) make it a valuable starting material for producing various derivatives, including soaps, polishes, and textile chemicals.
