What is ethanolamine (CAS 141-43-5)?

Ethanolamine, with the chemical formula C2H7NO, is a colorless or slightly yellow transparent liquid that exhibits the dual properties of both ammonia and alcohol. It belongs to the class of alkanolamines and is a product of ethanol molecule where one hydroxyl group (-OH) is replaced by an amino group (-NH2). Ethanolamine has good solubility in water and is miscible with many organic solvents, making it widely used in chemical production.

Ethanolamine is mainly classified into three types: monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA), named according to the number of hydroxyl groups replaced by amino groups in the molecule. Monoethanolamine contains one amino group and one hydroxyl group, diethanolamine contains two hydroxyl groups and one amino group, and triethanolamine contains three hydroxyl groups and one amino group. These three types of ethanolamine differ in properties, and therefore have different applications.

What is the structural formula of ethanolamine (CAS 141-43-5)?

Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is an organic chemical compound with the formula HOCH2CH2NH2 (C2H7NO). The molecule is bifunctional, containing both a primary amine and a primary alcohol.

What are the uses of ethanolamines?

In the chemical industry, ethanolamine is commonly used as a surfactant, emulsifier, dispersant, and raw material for synthetic resins and rubber.

In the pharmaceutical industry, ethanolamine is an important intermediate in the preparation of certain drugs, such as antihistamines and antidepressants.

In addition, ethanolamine can be used as an additive in metalworking fluids and as an auxiliary agent in the textile and leather industries.
