Description of key information

Additional information

Very limited information about the stability of dimethyltin dichloride (DMTC) was available. A single reliable study investigating the hydrolysis of the DMTC has been found to be reliable. In that study, which was conducted to OECD Guideline 111, the percentage hydrolysis of DMTC was less than 10% after incubation in buffer solutions pH 4.0, pH 7.0 and pH 9.0 and in Milli-Q water, for 5 days at 50 °C. A secondary reference (Bertolo (2001)) was discovered however it has not been possible to obtain the full report. That report that makes note that whilst the dimethyltin substance is hydrolytically stable, the substance itself is not. Given that the full study has not been reviewed this information is regarded as supporting. Therefore, based on the result of the key study, DMTC was considered hydrolytically stable and no further testing was performed.
