Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
THPC is expected to have a vapour pressure < 10e-6 hPa, as suggested by the read- across with its parent salt: THPS.
Key value for chemical safety assessment
Additional information
One study was performed on dried THPC (2010 Chilworth), but the method was not adapted to low vapour pressure measurements.
Because of the salt nature of THPC, hazard properties of chloride salt could be predicted to be equivalent to hazard properties of the sulphate salt (THPS). The read across with a similar substance as THPS is then considered as relevant.
The vapour pressure of dry THPS was determined by the vapour pressure balance method, according OECD 104 guideline, under GLP.
The test conditions and methods were well described and the study was therefore considered as reliable and gave
a vapour pressure of dry THPS < 2.6e-06 hPa at 25°C.
THPC is expected to have a vapour pressure < 10e-6 hPa, as suggested by the read across with its parent salt: THPS.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
