Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 following study was provided to fulfil the data requirement for melting point/freezing point:
BNT Chemicals (2010) Freezing point of Dibutyltindiacetate. Testing laboratory: BNT Chemicals GmbH, Parsevalstraβe 29, 06749 Bitterfeld. Report No.: BNT 5112-46/2. Report date: 2010-06-18
The study was an in-house test performed to a recognised guideline (EU Method A.1), using the method to determine the freezing temperature, the study was assigned a reliability score of 2 and considered reliable for assessment.
The following study was provided as a supporting study:
Acros Organics (2007) Material Safety Data Sheet dibutyltin diacetate pract. Bibliographic source: website https://fscimage.fishersci.com/msds/75959.htm. Owner company: Acros Organics N.V., One Reagent Lane, Fair Lawn, NJ 07410. Company study No.: ACC #75959. Report date: 2007-03-16
The data were sourced from a material safety data sheet and were assigned a reliability score of 4, the reliability of the data could not be assessed due to the limited information provided.
Overall the melting point of dibutyltin di(acetate) was determined to be 9 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
9 °C

Additional information

A reliability rating of 2 was assigned to the key study, BNT Chemicals (2010), according to the criteria of Klimisch, 1997 as the study was conducted in-house to recognised guidelines, however only summary reports were provided with minimal information on methods and results. The melting point was determined to be 9 °C.

Supporting information is also available from an Acros Safety data sheet (2007). The result was reported as 7-10°C

A reliability rating of 4 was assigned as the safety data sheet is secondary source of information and the accuracy of the data cannot be assessed from the limited reporting.
