Additional information

In an overview article from 1982 published data were compiled, discussed and critically evaluated by the International Union of Pure and Applied Chemistry, Analytical Chemistry Division, Commission on Equilibrium Data, J. Stary and J. 0. Liljenzin, Critical Evaluation of Equilibrium Constants Involving Acetylacetones and Its Metal Chelates.

The value can be considered reliable and suitable for use as the key study for this endpoint.
