Additional information

An n octanol-water partition coefficient value ranging from 9.268 -9.508, with an overall variance-weighted average value of 9.411 was determined for the substance using relevant test method. The result is considered to be reliable and was selected as key study. A log Kow value of 6 was reported in available sources which are used as supporting data. The study with the highest reliability was selected as key study.
