Description of key information

Estimation of the acid base properties based on the chemical structure.
Analytical Development Physical Chemistry, Schering AG Berlin. Study report No. A11331 (ADP 2002_336), dated 2002-11-25.
Result: The test compound can be considered as a neutral molecule in the pH range 2 to 10, which is of relevance for biological systems.

Key value for chemical safety assessment

Additional information

The test compound does not contain any functional group which can be protonated or deprotonated significantly in aqueous solution.

The pKa calculation with the computer program ACD/pKa DB gave no result.

Therefore, ZK 57564 is to be considered as a neutral molecule in the pH range 2 to 10, which is of relevance for aqueous biological systems.
