- Conclusions:
Freezing point of (S)-1,3,4-trihydroxybutan-2-one: -24.0°C (249.2 K)- Executive summary:
A freezing point temperature of -24.0°C (249.2 K) was determined as the average of both
main tests (Test 1: -23.9°C and Test 2: -24.1°C).
Therefore:
Freezing point of (S)-1,3,4-trihydroxybutan-2-one: -24.0°C (249.2 K)
Reference
Description of key information
The freezing point of (S)-1,3,4-trihydroxybutan-2-one was measured
according to the OECD guideline No.102
(method of the freezing temperature).
A temperature of -24.0°C (249.2 K) was determined as the average of both
main tests.
Therefore:
Freezing point of (S)-1,3,4-trihydroxybutan-2-one: -24.0°C (249.2 K)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -24 °C
