Applicant's summary and conclusion
- Conclusions:
- The melting point of the test item has been determined to be 133.4 ± 0.5 °C (406.5 ± 0.5 K).
- Executive summary:
The melting point is determined to be 133.4 ± 0.5 °C (406.5 ± 0.5 K), by differential scanning calorimetry, 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
