Hazard Information

General Description
A colorless liquid with a faint fishlike odor. Flash point 199°F. Corrosive to tissue. Toxic oxides of nitrogen are produced by combustion.
Reactivity Profile
N-AMINOETHYLPIPERAZINE(140-31-8) neutralizes acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.
Air & Water Reactions
Water soluble.
Hazard
Strong irritant to tissue.
Health Hazard
INHALATION: Burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. EYES AND SKIN: Extremely destructive to mucous membranes, upper respiratory tract, eyes and skin. Causes burns on short contact.
Potential Exposure
Used as an epoxy curing agent and making pharmaceuticals; synthetic fibers, and other chemicals.
Fire Hazard
Special Hazards of Combustion Products: Toxic fumes of NO x
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting.
Shipping
UN2815 N-Aminoethylpiperazined, Hazard class: 8; Labels: 8-Corrosive material
Incompatibilities
Solution is a strong base. Reacts with nitrosating agents (e.g., nitrites, nitrous gases, nitrous acid); capable of releasing carcinogenic nitrosamines. Incompatible with nonoxidizing mineral acids; strong acids; organic acids, acid chlorides; acid anhydrides; organic anhydrides; isocyanates, chloroformates, vinyl acetate; acrylates, substituted allyls; alkylene oxides; epichlorohydrin, ketones, aldehydes, alcohols, glycols, phenols, cresols, caprolactum solution; strong oxidizers. Contact with copper alloys, zinc or galvanized steel may cause violent reaction.
