Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Key result
- Temp.:
- ca. 20 °C
- Vapour pressure:
- ca. 0.46 Pa
- Conclusions:
- The estimated vapour pressure value of 2-aminoethanol hydrobromide is 0.46 Pa at 20°C. However, this measure was not repeatable.
Considering the estimated values of vapour pressure of 2-aminoethanol (35.6 Pa at 20.0°C) and 2-aminoethanol hydrobromide (non-salt form) (5.26 .10-6 Pa at 20.0°C) obtained with EPIsuite software (reports summary are in the attached document), we can assess that the 2-AMINOETHANOL HYDROBROMIDE owns a low vapour pressure.
Reference
Four measurements were firstly performed at temperatures between 23.0 and 45.0°C. However, only one determination was exploitable. Results obtained from determinations 3 and 4 showed amass[AM1] increase. Considering a pollution of the furnace, a pyrolysis was performed and two more determinations were performed. However, no exploitation was possible.
In conclusion, no value of vapour pressure could be determined for 2-AMINOETHANOL HYDROBROMIDEas no repeatable values were obtained. However, considering the vapour pressure obtained for determination 1 (0.46 Pa at 20.0°C) and estimated values of 2-aminoethanol (35.6 Pa at 20.0°C) and 2-aminoethanol hydrobromide (non-salt form) (5.26 .10-6Pa at 20.0°C) obtained with EPIsuite software, we can assess that the 2-AMINOETHANOL HYDROBROMIDE owns a low vapour pressure.

Additional information
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).
