Key result
Melting / freezing pt.:
189.4 °C
Conclusions:
Melting point: 189.4 ± 0.6ºC
Executive summary:

The study was conducted to determine the melting point of the test substance, according to the guidelines OECD Guideline No. 102, OPPTS 830.7200 and EEC Method A.1.

The melting point of test substance was determined by photocell detection using the “Buchi Melting Point B-545 instrument”. The melting point of test substance was determined to be 189.4 ± 0.6ºC.
