Description of key information

The dissociation constant (pKa) for N-[3-(dimethylamino)propyl]-C12-18(even numbered)-alkylamide has similar value at 8.5 at 20°C by read across to study about N-[3-(dimethylamino)propyl]-C18 unsaturated-alkylamide. It could reasonably be considered that chain length/insaturation has limited impact on pKa.
