The three individual measurements of tap bulk density gave the following results: 1.05, 1.04 and 1.07 g/mL, respectively. The resulting mean tap bulk density (rounded up) is 1.05 g/mL at 23 °C.

Description of key information

The substance  Reaction mass of 1,1'-(isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene] and 1,3-dibromo-2-(2,3-dibromo-2-methylpropoxy)-5-{2-[3,5-dibromo-4-(2,3,3-tribromo-2-methylpropoxy)phenyl]propan-2-yl}benzene has a bulk density of 1.05 g/mL at 23 °C (similar to EU A.3 method).

Key value for chemical safety assessment
