2-(2-Aminoethylamino)ethanol CAS 111-41-1 Use

(1)Industrial curing agents and synthetic intermediates

Epoxy resin curing agent: As a low-toxicity curing agent (replacing ethylenediamine), it is used in coatings and adhesives to enhance flexibility and adhesion.

Organic synthesis

Synthetic chelating agents (such as EDTA derivatives) and surfactants;

Prepare pharmaceutical intermediates (such as anti-tumor drug carriers).

(2) Gas purifying agent

Acidic gas removal: The removal of H₂S and CO₂ from natural gas and refinery gas, taking advantage of the reversible reaction between amino groups and acidic gases.

(3) Functional material additives

Metalworking fluids: Used as corrosion inhibitors and emulsifiers in the formulation of cutting fluids and antifreeze.

Polymer modification: To improve the catalytic foaming efficiency of polyurethane foam or as a toughening agent for nylon.

2-(2-Aminoethylamino)ethanol CAS 111-41-1 safety

Health risk:

Irritation: Moderately irritating to the skin, eyes and respiratory tract (rinse with clean water for 15 minutes after contact).

Acute toxicity: Oral LD₅₀ > 2,000 mg/kg in rats (low toxicity), but inhalation at high concentrations may cause pulmonary edema.

Environmental risk:

Toxic to aquatic organisms (48h-EC₅₀ < 10 mg/L), entry into water bodies needs to be prevented.

Protective measures:

When operating, wear impermeable gloves (made of nitrile), goggles and a gas mask.

Store in a cool and well-ventilated place, away from oxidants and strong acids.
