Applicant's summary and conclusion

Conclusions:
The pH of 1% w/v emulsion of the test item 1-bromo-3-methoxybenzene (CAS No2398-37-0)was 6.98 at27 °C.
Executive summary:

The pH determination of test item 1-bromo-3-methoxybenzene (CAS No 2398-37-0) was done following OECD guideline 122. pH of 1% w/v emulsion was measured with the help of pH meter and it was observed to be 6.98at 27 °C.Based on the value 3-bromoanisole (CAS No 2398-37-0) was considered to be neutral in pH.
