Applicant's summary and conclusion
- Conclusions:
- According to Dunn and Johansson (1983) the log Pow value for 4-bromoanisole is 3.05.
- Executive summary:
A log Pow value for 4-bromoanisole of 3.05 is given in Dunn and Johansson (1983). The shake-flask method was used for the experimental determination of log Pow. However, it is not clear, if the given log Pow of 4-bromoanisole is an experimental value from this publication, or if this value is from another source (see rationale for reliability inclucive deficiences). Hence, the information on the log Pow is considered as not reliable.
