- Conclusions:
- Under the study conditions, the freezing point of the test substance was determined to be -19.6°C.
- Executive summary:
A study was conducted to determine the freezing point of the test substance according to OECD Guideline 102, in compliance with GLP. A sample of the test substance was placed in a test tube and stirred continuously. As the test substance was cooled, its temperature was measured at regular intervals. As soon as the temperature remained constant for a minimum of three readings, this temperature was recorded as the freezing temperature. Under the study conditions, the freezing point of test substance was determined to be -19.6°C (Scymaris, 2017).
