Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Accoridng to the REACH-regulation Annex VII, section 7.5, Column 2 limit values of the vapour pressure based on a recognised calculation method is sufficient if the Melting point of the Substance is between 200 °C and 300 °C.
The melting point of By-product from Guanindinoacetic acid manufacturing.
The melting points of the main constituents are:
- Guanidinoacetic Acid: 268 °C
- Cyanoguanidine: 209 °C
- Sodium acetate: 324 °C
- Glycine: 225 °C
Therefore the a calculation of vapour pressure of these constituents is applicable. - Reason / purpose for cross-reference:

- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- QSAR Toolbox prediction.
- QSAR Toolbox: 4.4
- Database version: 4.4 - Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0.001 mBar
- Conclusions:
- Based on the calculations for the main constituents a vapour pressure of < 0.0011 mBar (0.000828 mmHg) at 25 °C can be assumed.
- Executive summary:
The vapour pressure of the main constituents of By-product from Guanindinoacetic acid manufacturing was calculated using the QSAR Toolblox (v. 4.4).
These values were taken as read-across source for the estimation of the vapour pressure of By-product from Guanindinoacetic acid manufacturing.
