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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Vapour pressure: 0.52 Pa at 25 deg C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.52 Pa
- at the temperature of:
- 25 °C
Additional information
All the vapour pressure estimations of tetrahydrophthalic anhydride, by (Q)SPR models, lead to results having the same order of magnitude.
Therefore was reasonable calculate the mean of them, to obtain a summary value suitable for the assessments of the above substance.
VP = (VPM+ VPN+ VPMY+ VPG) / 4 = 0.52 Pa at 25 deg C
As weight of evidence, the low vapour pressure of tetrahydrophthalic anhydride was confirmed by the experimental value of 0.045 Pa at 25 deg C, related to 1,2,3,6-tetrahydrophthalic anhydride, one of main isomers constituents of the tested UVCB substance.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).
