Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure of a substance is defined as the saturation pressure above a solid or liquid substance. In EU method A.4, seven different measuring methods are listed for the measurement of the vapour pressure of solids and liquids. However, the vapour pressure does not need to be measured due to technical reasons if calculations indicate that the value is significantly less than 10E-5 Pa. The calculated value (EPI Suite, Version 4.11, MPBVP v1.43) for Dioctyltin mercaptopropionate is 1.05E-006 Pa (Modified Grain Method) at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
Supporting QSAR
The vapour pressure of Dioctyltin mercaptopropionate was calculated using MPBPVP v1.43 (Sept 2010) 2000 U.S. Environmental Protection Agency. Given that the substance is an organic molecule within the molecular weight range of the training set compounds, the prediction is considered to be acceptable.
The vapour pressure of the test material was calculated to be 1.05E-006 Pa at 25 °C (Modified Grain method).
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.
