- Specific details on test material used for the study:
- - Expiration date of the lot/batch: 13.10.2017
- Analytical purity: 92% - Key result
- Melting / freezing pt.:
- < -30.2 °C
- Remarks on result:
- other: The crystallization was not observed during all measurements
- Conclusions:
- The freezing point (crystallization) of the test substance was not visually observed up to -30.4 ºC.
- Executive summary:
The freezing point of the test substance was determined in accordance with the OECD Guideline 102 with GLP. The method of crystalization tube in freezing mixture ice/acetone was used. The freezing point of the test substance was not visually observed up to -30.4 ºC.
Reference
During the test, the temperature of samples decreased at a constant rate, for measurement No. 1 to the temperature of -30.4 °C and for measurement No. 2 to the temperature of -30.2°C. The crystallization was not observed during all measurements.
According to Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, May 2008, Guidance for the implementation of REACH the study does not need to be conducted below a lower limit of –20 °C.
