Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Conclusions:
- For the pure solid guanidinium chloride the vapour pressure is expected to be much lower than 0.000005 Pa.
- Executive summary:
The vapour pressure of free guanidine is 293 Pa (HSDB). With Dalton's law the vapour pressure of free guanidine of an 1 molar solution in water calculates to 0.0000053Pa.
For the pure solid guanidinium chloride the intermolecular binding forces are much higher than for the solution in water, corresponding to the melting point of 188 °C. Therefore the vapour pressure is expected to be much lower than 0.000005 Pa
