Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
(96-h) LC50: >100 mg/L mortality Danio rerio
(96-h) LC50: 8500 mg/l QSAR
Key value for chemical safety assessment
Additional information
A 96-hour LC50 value of >100 mg/L and NOEC of ≥100 mg/L have been determined for the effects of the test substance on mortality of Danio rerio (tested as Brachydanio rerio). The result is expressed in terms of the estimated concentration of the parent substance based on measured DOC concentration of the stock solution.. However It is likely that the test organisms were primarily exposed to the hydrolysis products of the substance.
The read-across is supported by predictions for the hydrolysis product 2-methylpropylsilanetriol (96 h LC50 value of 8500 mg/L).
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.
