Applicant's summary and conclusion

Conclusions:
The pH of 1% w/v dispersion of the test item 3-Hydroxyacetophenone (CAS No121-71-1)was 6.16 at28 °C.
Executive summary:

The pH determination of test item 3-Hydroxyacetophenone (CAS No 121-71-1) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter and it was observed to be 6.16 at 28 °C. The pH suggested that 3-Hydroxyacetophenone (121 -17 -1) was acidic in nature.
