Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The vapor pressure of the test chemical was estimated using MPBPVP (v 1.43) from EPISUITE.

The vapour pressure of 2-octadecyl-1H-thioxantheno[2,1,9-def]isoquinoline-1,3(2H)-dione was estimated to be 5.99E-017 Pa at 25 deg C

It is reported as 0.000000001 Pa for the chemical safety assessment due to the limitation in the field.
