Applicant's summary and conclusion
- Conclusions:
- The pH of 1% w/v aqueous solution of the test item Nonan-2-one (CAS No. 821-55-6) was 4.57 at 23.8 °C.
- Executive summary:
The pH determination of test item Nonan-2-one(CAS No. 821-55-6) was done following OECD guideline 122. pH of 1% w/v aqueous solution was measured with the help of pH meter and it was observed to be 4.57 at 23.8 °C. Based on the value it was considered that
Nonan-2-one(CAS No. 821-55-6) was acidic in nature.
