Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bis(tri-n-butyltin)oxide is a slightly yellow liquid, which solidifies below -45°C

Key value for chemical safety assessment

Additional information

A weight of evidence approach was taken when assessing the melting point/freezing point of the substance. 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)

 

The data were all in agreement. All were assigned a reliability score of 2.
