Additional information

This molecule has log Kow values that range from <1 to 2.72. While calculating the PNECs, both values (1 and 2.72) were used in EUSES 2.1.1, and the ones yielding the lower (i.e,. the most conservative) PNECS are reported (i.e,. log Kow 1). Because it was necessary to experimentally generate a log Koc value, the value in EUSES 2.1.1, which via QSAR placed this molecule in the non-hydrophobic chemical class, was estimated to be 1.6 when the log Kow was designated as 1.
