Description of key information

The chemical structure of the test item shows different basic positions which can be protonated in an aqueous solution. The test item also consists of a mixture of several components and salts (see GLP-study No. 09L00406 from Competence Center Analytics, BASF SE). Therefore the determination of the dissociation constant of an aqueous preparation of the test item is not possible.

Key value for chemical safety assessment
