Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
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.).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
