Description of key information

The substance can be considered as a neutral molecule in the pH range 2 -10.

Key value for chemical safety assessment

Additional information

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, Advanced Chemistry Development Inc., Toronto Canada). Therefore, the substance can be considered as a neutral molecule in the pH range of 2 - 10.
