Description of key information

For complex mixtures (UVCB substances) the assessment of pKa is clearly complicated. Estimation of the individual components’ pKa values, if appropriate, should be considered. Therefore, the pKa for the constituent present in the highest proportion is provided.
pka = 15.91 ± 0.46 (most acidic temperature 25 ºC)
pka = 4.7 ± 0.40 (most basic temperature 25 ºC)
