Description of key information

The substance can be considered as a neutral molecule in the pH range 2 -10, which is of relevance for biological systems.

Key value for chemical safety assessment

Additional information

The chemical structure of the substance does not show any groups, which can be protonated or deprotonated in the biologically relevant range of pH 2 to pH 10. Except for the aliphatic OH-group the substance does not contain any functional group which can be protonated or deprotonated significantly in aqueous solution. For the aliphatic hydroxyl group a pKa value of 11.2 was calculated with the computer program (ACD/pKa DB). Therefore, the substance can be considered as a neutral molecule in this pH range.
