Purity: 98.0%
Description: Clear, pale yellow liquid
Expiry/Retest date: 06 Jun 2019
Molecular Weight: 194.27
Molecular Formula: C12H18O2
Density (g/cm3 at 20°C): 0.994-0.996 (20°C) - Key result
- Melting / freezing pt.:
- < 20 °C
- Conclusions:
- The sample was held between -25.5 to -27°C for approximately 21 hours. No freezing was observed, therefore the result has been reported as < -20°C.
- Executive summary:
The freezing point of Vetimoss was determined according to OECD guideline 102. The sample was held between -25.5 to -27°C for approximately 21 hours. No freezing was observed, therefore the result has been reported as < -20°C.
