Additional information

In accordance with REACH Regulation 1907/2006, Annex VIII, 9.3.1 Column 2, adsoprtion/desporption has not been determined, based on low potential for adsorption (the substance has a low octanol water partition coefficient of 1.88 and the substance is not hydrolytically stable).


The Henry's Law constant of 2.18 Pa-m3/mole indicates that the substance is not significantly volatile from surface water


Distribution in environmental compartments has been calculated using a Fugacity model according to Mackay, Level III. Distribution in various environmental compartments is estimated as: Air – 0.462%; Water – 40.3%; Soil – 59.2% and Sediment - 0.0907%. Similar distribution modeling on the hydrolysis product of the substance indicated the following distribution: Air – 0.0000574%; Water – 19.9%; Soil - 0% and Sediment - 0.1179%. Refined modelling has been undertaken on the analogue of the substance, methyltetrahydrophthalic anhydride (MTHPA) as part of the OECD SIDS initial assessment report (Katsuo K.).
