Description of key information

Key study: Read-across from experimental results on the two main components of the substance Reaction mass of 2,6-di-tert-butylphenol and 2,4,6-tri-tert-butylphenol. 
2,6-di-tert-butylphenol pKa= 11.7 at 25 ºC
2,4,6-tri-tert-butylphenol pKa = 12.2 at 25 ºC

Key value for chemical safety assessment

Additional information

Key study: Read-across from experimental results on the two main components of the substance Reaction mass of 2,6-di-tert-butylphenol and 2,4,6-tri-tert-butylphenol.

Based on published experimental data the read-across approach is applied.

2,6-di-tert-butylphenol pKa= 11.7 at 25 ºC

2,4,6-tri-tert-butylphenol pKa = 12.2 at 25 ºC
