Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A weight of evidence approach was taken in determining the density of bis(tributyltin) oxide from the available data. The data were all in agreement, with the exception of one which was reported slightly lower than the general consensus, however the deviation was very small (1.14 compared to 1.17).

The relative density of bis(tributyltin) oxide was reported to be 1.17 at 25 °C.

Key value for chemical safety assessment

Additional information

A weight of evidence approach was taken when assessing the relative density. The data used to fulfil this data requirement were all sourced from the following peer reviewed handbooks:

 

Lewis, RJ (2002), Hawley's Condensed Chemical Dictionary, 14th Edition

Verschueren, K (2001) Handbook of Environmental Data on Organic Chemicals (4th Edition)

Gangolli, S. ed. (2005) Dictionary of Substances and Their Effects (DOSE, 3rd Electronic Edition)

Prager, JC (1998) Environmental Contaminant Reference Databook, Volumes 1-3

 

Gangolli S ed. (2005), was the only source to report a different value at 1.14. All were assigned a reliability score of 2.
