Executive summary:

Method

The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.

Results

The DSC analysis of the test substance is characterized by a glass transition at about 200 °C followed by decomposition of the product from 230 °C.

Conclusion

The test item is a solid at 1013 hPa and 20 °C.
