Applicant's summary and conclusion

Conclusions:
The melting point of the test item has been determined to be -4.6 ± 0.5 °C (269 ± 0.5 K).
Executive summary:

The determination was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 and Method 830.7200 of the OPPTS Guidelines, March 1998.

Conclusion

The melting point of the test item has been determined to be-4.6 ± 0.5 °C (269 ± 0.5 K).
