Method

Test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD guideline 102.

Results

Melting of test substance between 206 - 236 °C (onset at 221.9 °C, enthalpy = -90.5 J/g), followed by decomposition.

Conclusion

Test item is solid at 1013 hPa and 20 °C.
