Applicant's summary and conclusion
- Conclusions:
- The pH of 1% w/v dispersion of the test item 3'-nitroacetophenone (CAS No121-89-1)was 3.81 at 29.1 °C.
- Executive summary:
The pH determination of test item 3'-nitroacetophenone (CAS No 121-89-1) 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 3.81at 29.1 °C. Based on the value, 3'-nitroacetophenone (CAS No 121-89-1) was considered to be acidic in nature.
