04 · Handling and storage

Storing and handling Aminoethylpiperazine

Storage conditions

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Source: Hazardous Substances Data Bank (HSDB)

Incompatible materials

Materials to avoid: oxidizing agents

Source: Hazardous Substances Data Bank (HSDB)

Reactivity

N-AMINOETHYLPIPERAZINE 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.
