Description of key information

The dissocitaion constant was not determined for DAPD directly, instead, the component R-59 was used as surrogate. The results found for R-59 were assumed to be valid for DAPD.

The pKa for the non-methylated 20% component (R-59) of the submission substance was determined to be approximately 1.4.
