A density of 1.3 g/cm³ was reported.
Executive summary:

A density of 1.3 g/cm³ was reported in Sax's Dangerous Properties of Industrial Materials (1992).

Description of key information

The density is in the range of 1.27 and 1.38 g/cm³ at ambient temperature.

Key value for chemical safety assessment

Relative density at 20C:
1.3

Additional information

A literature search was conducted and the available published data reviewed. In a weight of evidence approach the literature values were evaluated. Three independent literature sources were found. The density was determined to be 1.27 g/cm³ (CRC Handbook, 2008), 1.3 g/cm³ ( Sax's Dangerous Properties of Industrial Materials, 1992) and 1.38 g/cm³ (Hommel Handbook, 2009) at 20 °C. All 3 independent values are in the same range and therefore regarded as reliable. A density of 1.3 g/cm³ was chosen as key value.
