Conclusions:

The test item Di aluminium tris [2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)benzoate] started decomposing at 334.5 °C - 338 °C with colour change from red to black. The decomposition range was found to be 334.5 °C -338 °C at 972.1 hPa, and hence it was not possible to determine the melting point.

Executive summary:

The melting point determination of Test item Di aluminium tris [2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)benzoate] (CAS No. 15876-39-8) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test item started decomposing at 334.5 °C - 338 °C with colour change from red to black . The decomposition range was found to be 334.5 °C -338 °C at 972.1 hPa, hence it was not possible to determine the melting point.
