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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are two studies available with a reliability rating of 2 according to the criteria of Klimisch et al., 1997; the Tremain (2004) study is the most recent and was therefore selected as the key study.
In the key study, tetrabutyltin was determined to have a vapour pressure of 0.26 Pa at 25 ºC from a study performed using OECD Guideline 104.
Key value for chemical safety assessment
- Vapour pressure:
- 0.26 hPa
- at the temperature of:
- 25 °C
Additional information
In the Tremain (2004) study, tetrabutyltin was determined to have a vapour pressure of 0.26 Pa at 25 ºC from a study performed using OECD Guideline 104 (effusion method: vapour pressure balance).
In the supporting study, Miklautz, 1989, Tetrabutyltin was determined to have a vapour pressure of 0.14 Pa at 25 ºC from a study performed using OECD Guideline 104. 95 % CL: 0.13 - 0.16 Pa.
