- ca. 23.5 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Remarks on result:
- other: Average of 4 run studies
- Conclusions:
- Under study conditions, given that the second endotherm could indicate boiling of a different component of the test substance, the melting point of the test substance is considered to range from from 23.5 to 100°C.
- Executive summary:
A study was conducted to determine the melting point of the test substance using Differential Scanning Calorimetry (DSC) according to EU Method A1 and OECD Guideline 102, in compliance with GLP. During the study, the first endotherm occurred at approximately 23°C, which was suspected to be due to the melting of the test substance. The second endotherm occurred at approximately 100°C, which was concluded by the study author to be either associated with the loss of water or due to the UVCB nature of the test substance, indicating the melting of a different component. The melting point of the test substance was concluded by the author to be 23.5°C. (Chilworth, 2017). Under study conditions, given that the second endotherm could indicate boiling of a different component of the test substance, the melting point of the test substance is considered to range from from 23.5 to 100°C.

Comment
The first endotherm occurred at approximately 23°C. It was thought that the first endotherm was due to the melting of the test substance. The second endotherm occurred at approximately 100°C, this could be associated with the loss of water or as the product is known to be of Unknown or Variable Composition, Complex Reaction Products and Biological Materials (UVCB Substance), it is possible that the second endotherm is due to the melting / boiling of a different component.
Description of key information
The melting point of the test substance was determined using the Differential Scanning Calorimetry (DSC) method according to OECD Guideline 102 and EU Method A.1(Chilworth, 2017).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 23.5 °C
Additional information
Due to the UVCB nature of the test substance and multiple observed endotherms, the overall melting point of the test substance can be considered to range from 23.5 to 100 °C at 101325 Pa.
