Description of key information

According to an experimental measure made by MLPC, relative apparent density of ETU (imidazolidine-2-thione)  is about 0.4524 g/cm3, whereas the crystal volumic mass is about 1.36 g/cm3

Key value for chemical safety assessment

Relative density at 20C:

Additional information

According to ACD labs, ETU (imidazolidine-2-thione) density is about 1.26-1.28 g/m3 (crystal density).A study was performed at central laboratory of MLPC (Rion des Landes France) to investigate the relative density of EKALAND ETU (imidazolidine-2 -thione). The study was made with a protocol described in ASTM 1895. The relative apparent density of ETU is determined to be about 0.4512 at 20°C
