Description of key information
Relative density: 1.4732 at 20 °C (OECD Guideline 109, pycnometer method)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.473
Additional information
In another study performed using according to the same method a relative density of 1.3476 at 20 °C was measured on a less pure test item, supporting the result obtained from the key study.
In this same study, bulk density and tap density were determined to be 0.6687 and 0.7810 g/mL, respectively (OPPTS 830.7300, pour and tap method)
