Description of key information

A weight of evidence approach was considered to be the most appropriate conclusion from the three data sources available. As two of the sources concurred the value 6.08 was selected for the pKa of 2,4,6-tribromophenol; one of which stated this figure as experimentally derived. All reports cite different sources of the data.
