Description of key information

The density of (3-Ammonio-4-methoxyphenyl)(2-hydroxyethyl)ammonium sulphate was 1.541 g/mL corresponding to 1541 kg/m3 at 20°C, measured by pycnometer method (OECD 109).

Key value for chemical safety assessment

Additional information

The density of (3 -Ammonio-4 -methoxyphenyl)(2 -hydroxyethyl) ammonium sulphate was determined following guideline OECD 109 (Density of Liquids and Solids) with pycnometer using the displacement method and GLP. The test was run in triplicate at a test temperature of 20˚C.

Approximately 3 g of the test substance was placed into the pycnometers. The pycnometers were filled with the vehicle and kept for 30 min in the refrigerated circulator. The filled pycnometers were weighed and the density of test item was calculated. 

The density of the test item was 1.541 g/mL corresponding to 1541 kg/m3.
