Monoethanolamine is an organic chemical compound with the formula HOCH2CH2NH2 or C2H7NO.
Monoethanolamine is bifunctional, containing both a primary amine and a primary alcohol.

Monoethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia.
Monoethanolamine molecules are a component in the formation of cellular membranes and are thus a molecular building block for life.

Monoethanolamine was thought to exist only on Earth and on certain asteroids, but in 2021 evidence was found that ETA molecules exist in interstellar space.
Derivatives of Monoethanolamine are widespread in nature; e.g., lipids, as precursor of a variety of N-acylethanolamines (NAEs), that modulate several animal and plant physiological processes such as seed germination, plant–pathogen interactions, chloroplast development and flowering, as well as precursor, combined with arachidonic acid C20H32O2 20:4, ω-6), to form the endocannabinoid anandamide.

Monoethanolamine is produced by treating ethylene oxide with aqueous ammonia; the reaction also produces diethanolamine and triethanolamine.
The ratio of the products can be controlled by the stoichiometry of the reactants.

The Monoethanolamines comprise a group of amino alcohols.
Monoethanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes (particularly those of prokaryotes); e.g., phosphatidylethanolamine.

Monoethanolamine is commonly called monoethanolamine or MEA in order to be distinguished from diethanolamine (DEA) and triethanolamine (TEA).

Monoethanolamine is used as feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, corrosion inhibitors, and chemical intermediates.
Monoethanolamines can scrub combusted-coal, combusted-methane and combusted-biogas flue emissions of carbon dioxide (CO2) very efficiently. MEA carbon dioxide scrubbing is also used to regenerate the air on submarines.

Solutions of Monoethanolamine in water are used as a gas stream scrubbing liquid in amine treaters.
For example, aqueous Monoethanolamine is used to remove carbon dioxide (CO2) and hydrogen sulfide (H2S) from various gas streams; e.g., flue gas and sour natural gas.

Monoethanolamine is often used for alkalinization of water in steam cycles of power plants, including nuclear power plants with pressurized water reactors.
This alkalinization is performed to control corrosion of metal components.

In such application, ETA is a key ingredient of so-called "all-volatile treatment" of water (AVT).

Monoethanolamine is a first generation monoethanolamine with antihistaminic property.
Monoethanolamine competes with free histamine for binding at the histamine (H)-1 receptor thereby acting as an inverse agonist that combines with and stabilizes the inactive form of the H1-receptor thereby shifting the equilibrium toward the inactive state.

This leads to a reduction of the negative symptoms brought on by H1-receptor binding.
