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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (trimethoxy(2-methylpropyl)silane: 190 Pa at 25°C (QSAR)
Vapour pressure ((2-methylpropyl)silanetriol): 0.00294 Pa at 25°C (QSAR)
Key value for chemical safety assessment
- Vapour pressure:
- 190 Pa
- at the temperature of:
- 25 °C
Additional information
A vapour pressure of 190 Pa at 25°C was determined for the substance using an appropriate QSAR predictive method. The result is considered to be reliable and is selected as key. Trimethoxy(2-methylpropyl)silane was reported to have a vapour pressure value of 300 Pa at 20°C in a secondary source to which no reliability could be assigned. This value supports the key study.
The vapour pressure of the hydrolysis product was determined to be 0.0029 Pa at 25°C using an appropriate QSAR estimation method.
A measured vapour pressure of 12 790 Pa at 20°C is available for methanol (OECD, 2004)
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.
