Description of key information
Additional information
Aminoethylpiperazine is a clear liquid, freezing at a temperature of -19 °C and boiling at 220.4°C. The substance has a vapor pressure of 5.2 Pa and liquid density of 0.98 g/cm3 at 20 °C. Aminoethylpiperazine has a flash point (closed-cup) of 99 °C, and therefore is not classified as a flammable liquid. The measured octanol-water partition coefficient (log Kow) is -14.8, which is consistent with the miscibility of aminoethylpiperazine in water. The substance possesses three amino groups, the ionization of which in aqeous media is defined by pKa values of 4.3, 8.5, and 9.6.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
