Executive summary:

Method

The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the Directive EC 440/2008 Method A.1. and according to the OECD Test Guideline 102 (1995).

Results

The imbibition water/solvent release was observed between 25-130 °C, followed by decomposition of the product between 290 -430 °C (onset at 326.7 °C; enthalpy = 1931.4 J/g).

Conclusion

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