Registration Dossier
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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 1800 Pa (dichlorotetramethyldisilane)
Vapour pressure: 593 Pa (trichlorotrimethyldisilane)
Vapour pressure: 421 Pa (tetrachlorodimethyldisilane)
Key value for chemical safety assessment
Additional information
No measured data is available for the substance. However, measured data is available for two of the three constituents of the substance. Vapour pressure values of 593 and 421.3 Pa are available for 1,1,2-trichloro-1,2,2-trimethyl-Disilane and 1,1,2,2-tetrachloro-1,2-dimethyl-Disilane respectively, for sources to which reliability could not be assigned. No measured values were available for 1,2-dichloro-1,1,2,2-tetramethyl-Disilane, so a validated QSAR model was used to determine a value of 1800 Pa.
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.
