Abiotic degradation

No determination was possible according to Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004, for the following reason: - During preliminary investigations for the water solubility test, it was concluded that the test item hydrolyses immediately upon contact with water. Substances which hydrolyse rapidly in contact with water are not suitable for determination using Method 111. In accordance with Annex XI section 2 of the Regulation EC 1907/2006, testing for a specific endpoint may be omitted, if it is technically not possible to conduct the study as a consequence of the properties of the substance. In the water solubility test, the sample was initially a translucent suspension and after 10 minutes a small amount of white flocculent was observed. Analysis by MS indicated significant differences between the reference and sample solutions. The indications are that the compound is insoluble and hydrolyses immediately on contact with water.

Biotic degradation

Based on read-across from a number of structurally similar compounds, it can be concluded that diisotridecyl 3,3'-[(dibutylstannylene) bis(thio)] dipropionate is not readily biodegradable. Simulation tests are not available. In the absence of such information diisotridecyl 3,3'-[(dibutylstannylene) bis(thio)]dipropionate is concluded to be stable to biodegradation.
