Description of key information
In a weight of evidence approach 4 values from databases/publications/handbooks were taken into account. The CRC handbook reported the density to be 1.105 g/cm3 at 25 °C and publications taken from the REAXYS database reported values of 1.1101, 1.1084 and 1.115 g/cm3 at 20 °C. Therefore the relative density was determined to be in the range of 1.1084 to 1.115 at 20 °C
Key value for chemical safety assessment
- Relative density at 20C:
- 1.11
