Description of key information

Estimated dissociation constants in water

-SO3 -: -2.5 > pKa > -3.0 acidic (2x)

Ph-NH-Ph: pKa ≈ 0.8 basic (4x)

Triaz-Morph.: -1 < pKa < 2 basic (2x)

Key value for chemical safety assessment

Additional information

Under environmental conditions the substance dissociates completely in water
