Description of key information

pKa = 10.25 at 20ºC (SPARC calculation)

pKa = 10.23 at 25ºC (Lide, 2000)
pKa = 10.13 (ACD/Labs calculation)
The values indicate there are no functional groups which are associated with dissociation behaviour at relevant environmental conditions.

Key value for chemical safety assessment

pKa at 20°C:

Additional information

All measured and calculated dissociation constant values indicate that the pKa is >10. This is outside the environmentally significant range of 5 to 9.

A pKa of 10.25 should be used in the Chemical Safety Assessment.
