- other: calculated
Applicant's summary and conclusion
- Conclusions:
- The calculated vapour pressure of the substance is < 0.001 Pa at 20°C.
- Executive summary:
The vapour pressure of the substance was calculated with the Software / MPBPWIN 1.43 (Syracuse Research Corporation).
It was found to be < 0.001 Pa at 20°C.
This molecule cannot be calculated directly with Syracuse. The Syracuse calculation on a similar structure about half the size gave a vapour pressure less than 0.001 Pa. The vapour pressure of the substance must be even lower.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
