Description of key information

According to result from QSAR the substance falls within the applicability domain (2,2-bis(hydroxymethyl)butanoic acid is organic monoconstituent substance with molecular weight of 148.16) and therefore the predicted value (Koc: 10.0 L/kg, Log Koc: 1.0) can be considered as reliable taking into account the statistical information for the MCI (Molecular Connectivity Index, first-order) training and validation datasets.
The predicted value was used for Chemical safety assessment (CSA) and is considered as adequate and no additional information is required.
