Specific details on test material used for the study:
- Batch n°: DR74271215
- Production release date: 30 November 2015
- Expiry date: 30 December 2018
- Purity (on dry basis): 98.2%, water content: 0.05%
Key result
Melting / freezing pt.:
< -20 °C
Decomposition:
no
Sublimation:
no
Remarks on result:
other: Mean of at least two measurements which are in the range of the estimated accuracy

The sample did not freeze at -20.0°C.

Conclusions:
The freezing point of the substance is determined to be < -20°C since the sample did not freeze at -20.0°C.

Description of key information

A K1 GLP study was performed according to OECD guideline 102 and EU Method A.1. The freezing point of the test substance was found to be <-20 °C (Dekra, 2017).

Key value for chemical safety assessment

Additional information

The freezing point of the test item was determined to be <-20°C.
