Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance rapidly decomposes in contact with water forming a range of breakdown products. The test substance can only be analysed after derivatisation, but using derivatisation, a distinction between intact test substance and breakdown products can no longer be made, this is a prerequisite for the hydrolysis study. In addition, the expected water solubility is very low and at these low levels it is often difficult if not impossible to prevent adsorption of test substance to the vials or containers used. In conclusion, the hydrolysis of the test substance could not be performed (Baltussen E (2010) Determination of Physico-Chemical Properties of Monobutyltin Trichloride. NOTOX project no. 492798).
Additional information
Until very recently, the substance was indeed considered to be highly insoluble in water and to hydrolyse rapidly and as such the statement above had been submitted. As part of the ongoing CoRAP evaluation additional investigations are currently being conducted and studies are still ongoing. Anecdotal evidence suggests that the substance may be more soluble than originally thought and has been shown not to rapidly hydrolyse. Work is currently ongoing to clarify the behaviour of the substance and once the appropriate data are available, the CSR and the corresponding Key Information will be updated accordingly once all the relevant information on the behavior of the substance in the environment including its water solubility and partition coefficient are available.
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.
