N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine

N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine is a polyamine compound with the molecular formula C6H18N4 and CAS number 112-24-3. This chemical substance has a molecular weight of 146.23 g/mol and contains four amino groups in its structure. It is classified as a corrosive substance with acute toxicity properties and requires careful handling due to its hazardous nature.

N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine is typically a liquid or viscous substance at room temperature with strong alkaline properties due to its multiple amino groups. The compound is highly soluble in water and polar solvents, forming strongly basic solutions. It has a characteristic amine odor and can appear colorless to slightly yellow. The presence of four nitrogen atoms makes it highly reactive with acids and electrophilic compounds.

N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine is primarily used as a curing agent for epoxy resins and polyurethane systems in industrial applications. It serves as an intermediate in the synthesis of chelating agents, corrosion inhibitors, and specialty chemicals. The compound is also utilized in the production of paper wet-strength agents, textile auxiliaries, and as a cross-linking agent in polymer chemistry applications.

Safe handling requires wearing appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Skin Corr. 1B classification. Work in well-ventilated areas or use local exhaust ventilation to prevent inhalation exposure. Avoid direct skin and eye contact as the substance can cause severe burns and sensitization. Use appropriate tools to prevent splashing and ensure emergency eyewash stations are readily accessible.

Store N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Keep away from acids, oxidizing agents, and reactive compounds that could cause dangerous reactions. Use corrosion-resistant containers and ensure proper labeling with hazard information. Implement appropriate spill containment measures and restrict access to authorized personnel only.

Immediate action is required due to the substance's corrosive nature. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. For eye contact, flush immediately with water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. Seek medical attention promptly for all exposure routes, especially skin and eye contact due to potential severe burns.

Disposal must comply with local and national hazardous waste regulations due to its corrosive and toxic properties. Do not discharge into sewers, waterways, or the environment. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require neutralization before disposal, but this should only be performed by trained professionals. Maintain proper documentation for waste tracking and regulatory compliance.

Transportation is regulated under ADR Class 8 (corrosive substances) with Packing Group II classification, indicating moderate danger level. Use appropriate UN-specification packaging designed for corrosive liquids and ensure proper hazard labeling with GHS05 and GHS07 pictograms. Comply with dangerous goods regulations for documentation, vehicle requirements, and driver training. Segregate from incompatible materials during transport and follow emergency response procedures for spills or accidents.

Yes, the substance is subject to REACH regulation for registration and authorization within the EU market. It must comply with CLP regulation for classification, labeling, and packaging requirements, displaying appropriate hazard pictograms and safety information. While not currently listed as SVHC, it requires safety data sheets and risk assessments due to its hazardous classification. Industrial users must implement appropriate risk management measures and worker protection protocols.
