Ethanolamine
Introduction
1.CAS:141-43-5
2.Ethanolamine, also called 2-aminoethanol or monoethanolamine (MEA), is a viscous, hygroscopic organic chemical compound that is both a primary amine (due to an amino group) and a primary alcohol (hydroxyl group). Used as a surfactant, fluorimetric reagent, and to remove CO2 and H2S from natural gas and other gases. Ethanolamine is widely distributed in biological tissue and is a component of lecithin. Ethanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes.
