NH2CH2CH2OH

2-Aminoethanol, also known as ethanolamine or monoethanolamine (MEA), is an organic chemical compound with the formula NH2CH2CH2OH. It is a colorless, viscous liquid with an ammonia-like odor. It is a primary amine and a primary alcohol, making it a bifunctional molecule. 2-Aminoethanol is miscible with water and soluble in many organic solvents.

This compound is widely used in various industrial applications. It serves as a precursor in the synthesis of detergents, surfactants, pharmaceuticals, and agrochemicals. In the oil and gas industry, it is employed as a gas sweetening agent to remove acidic gases like hydrogen sulfide and carbon dioxide from natural gas and refinery streams. It is also used as a pH adjuster in cosmetics and personal care products, and as an emulsifier in waxes and polishes.

2-Aminoethanol can be synthesized through the reaction of ethylene oxide with ammonia. It is a relatively stable compound but can react with strong oxidizing agents. Its corrosive nature requires careful handling and appropriate personal protective equipment. In biological systems, it is a component of phospholipids and is involved in various metabolic processes.
