Aminoethylpiperazine
chemical compound
Aminoethylpiperazine (AEP) is a derivative of piperazine. This ethyleneamine contains three nitrogen atoms; one primary, one secondary and one tertiary. It is a corrosive organic liquid and can cause second or third degree burns. Aminoethylpiperazine can also cause pulmonary edema as a result of inhalation. It is REACH and TSCA registered.
Production
Ethylene dichloride is reacted with ammonia as a main method of production. This process produces various ethylene amines which can then be purified by distillation. These include ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, other higher homologues and aminoethyl piperazine.
AEP is also manufactured by reacting ethylenediamine or ethanolamine/ammonia mixtures over a catalyst.
Epoxy resin curing agent
A key use of AEP is as an epoxy curing agent.

Why this record matters
“Aminoethylpiperazine” is worth following because a concise public description often conceals a longer documentary argument. Here, Aminoethylpiperazine, chemical and compound provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 14, 2026. The linked authority identifier is Q3887815. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
