Description of key information

The mean density of AZDN is determined to be 1.098 kg/m3, or 1.098 g/cm3 with standard deviation of 0.004 (using the pycnometer method). 

Key value for chemical safety assessment

Relative density at 20C:
1.098

Additional information

The determination of the physicochemical properties of AZDN E also known as 2,2-azobis(isobutyronitrile) was investigated which included an investigation to determine its relative density. The result (using the pycnometer method) is calculated to be 1.098. A second study determined the specific gravity of azobis (cyanoisopropyl) (synonym of AZDN) which calculated the density; the result was given as 'specific gravity' at a value of 1.05.
