- Key result
- Melting / freezing pt.:
- >= 85 - <= 110 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Conclusions:
- The DSC measurements (25 - 500 °C) showed that the test item had a melting range of 85 - 110 °C.
- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1. The melting range was determined by differential scanning calorimetry. The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. The DSC measurements showed that the test item had a melting point in the range 85 -110 °C.
Reference
Three DSC measurements with a heating rate of 10 K/min showed a multithermal endothermal effect (melting) in the temperature range of 85 - 110 °C.

Description of key information
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1. The melting point / melting range was determined by differential scanning calorimetry (DSC 25 - 500 °C). The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. The test item had a melting range of 85 - 110 °C under atmospheric conditions.
Key value for chemical safety assessment
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.
