Executive summary:

The density of test item was determined using a helium pentapycnometer. The guideline is not stated in the report, but the study was performed according a standard method equivalent to the OECD 109 guideline.

This is a non-GLP experimental study and there are minor restrictions in reporting but it is otherwise acceptable as the key study for this endpoint.

The density of uverithe is 4.4 g/cm3.

Description of key information

The density of Uverithe is 4.4 g/cm3.

Additional information

The density of test item was determined using a helium pentapycnometer (Schefter 2016).
