Description of key information
The following key study was provided to assess the boiling point of dibutyltin maleate:
Walker JA & White DF (2010) DETERMINATION OF GENERAL PHYSICO-CHEMICAL PROPERTIES. Testing laboratory: Harlan Laboratories Limited, Shardlow Business Park, Shardlow, Derbyshire, DE72 2GD, UK. Owner company: Organo Tin REACH Consortium, c/o ReachCentrum, Avenue E. Van Nieuwenhuyse 6, B-1160, Brussels, BELGIUM. Report No.: 3109/0048. Report date: 2010-08-10
The study was assessed to be reliable and adequate to fulfil the data requirement and was assigned a reliability score of 1. The test item was reported to decompose from 260°C (533 K) at 100.8 kPa, by differential scanning calorimetry, using ASTM E537-86, designed to be compatible with Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 and Method A2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
As the test item decomposed, no value for boiling point could be determined.
The following was provided in support of the key study:
Gelest Inc. MSDS (2003) Di-n-butyl(maleate)tin - SND3320. Bibliographic source: http://67.217.111.136/msds/SND3320.pdf. Owner company: Gelest, Inc., 11 East Steel Rd., Morrisville, PA 19067. Report date: 2003-02-10
The supporting data provided a boiling point of >200 °C.
Key value for chemical safety assessment
Additional information
Value used for CSA:not applicable due to decomposition
A reliability rating of 1 was assigned to the key study, Walker & White (2010), according to the criteria of Klimisch, 1997 as the study was conducted in accordance with recognised guidelines and GLP. No boiling point could be determined as the test substance decomposed from 260 °C.
Supporting information is also available from a Safety data sheet (Gelest, 2010). As the study was a secondary source, and the reliability of the data could not be assessed from the limited reporting, the data was assigned a reliability score of 4 (not assignable). The results contained in this is stated as being >200°C. A reliability rating of 4 was assigned as the safety data sheets are secondary source information.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
