Description of key information
Additional information
Sodium 2-biphenylate is not stable in the environment. The substance will dissociate on contact with water forming NaOH and 2-phenylphenol. Under environmentally relevant conditions the substance will dissociate and the neutral from of 2-phenylphenol will prevail. The available studies on the adsorption potential of 2-phenylphenol determined log KOC values <3 indicating a moderate mobility of the substance in soil. Supporting QSAR calculations with sodium 2-biphenylate predicted a low adsorption potential of the substance (estimated log Koc of 2.72 based on log Pow).
The water solubility of 2-phenylphenol is pH dependent. At environmentally relevant pH (pH 5-9) the water solubility is < 1 mg/L (range: 0.53 – 0.64 mg/L at pH 5-9). Transport and accumulation in natural water bodies is considered not relevant. Volatilisation of sodium 2-biphenylate or 2-phenylphenol from STP or natural water bodies is not likely due to the low volatilization potential (VP 1.2 Pa and 0.474 Pa at 20 °C, respectively). However, the substance is not expected to accumulate and persist in the environment due to its ready biodegradability.
