Description of key information
The result relates to crystal density (in g/cm3).
The substance is much denser than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.93
Additional information
No experimental study is available for the substance.
From several literature sources (handbook and secondary sources), in a Weight-of-Evidence approach, the density values range between 1.915 and 1.937 g/cm/3, relating to crystal density, eg true, not bulk, density. The handbook value of 1.93 g/cm3 (giving a relative density D20/4 of 1.93, unitless, assuming water density at 4°C is ca 1.0) is retained as key data.
