Additional information

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 is not likely to be present in the atmosphere, due to the very low estimated vapour pressure of 3.31 x 10^-11 Pa (at 25 °C, EPISUITE, MPBPWIN v1.43, modified Grain method). Hence, indirect photodegradation in air is no important degradation pathway for the substance. Hydrolysis is not a relevant pathway, since the substance is highly insoluble in water and hydrolysable functional groups are missing.
