Manufacturer Colonial Chemical Inc.
Sample ID 53467J16
Received on November 22, 2016
Tested on January 3, 2017 - Key result
- Melting / freezing pt.:
- -42.1 °C
- Conclusions:
- A freezing point was evident in the sample with an average of 250.5°K (-22.6°C) (Onset). Two melting points with average onsets of 208.7°K (-64.4°C) and 231.0°K (-42.1°C) were evident on heating. The 231.0°K (-42.1°C) melting point was the main melting point.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
