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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
methyldiacetoxyisopropoxy silane: 199 Pa at 25 °C (QSAR)
hydrolysis product (methylsilanetriol): 0.153 Pa at 25 °C (QSAR)
Key value for chemical safety assessment
Additional information
The vapour pressure of the substance was determined by QSAR calculation using ACD and EPISuite (MPBPVP v1.43). In the description of the ACD calculation the necessary applicability domain assessment is missing and the recommended reliability is RL=4. Therefore this study was used in a weight of evidence approach together with the MPBPVP calculation (RL=2), which uses the experimentally determined boiling point (171.3 °C at 102.4 kPa) as input data. The vapour pressure of the hydrolysis product methylsilanetriol was determined by QSAR calculation using EPISuite (MPBPVP v1.43).
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.
