Applicant's summary and conclusion

Conclusions:
The pH determination of test item Dimethyl sulphone (CAS No 67-71-0) was done following OECD guideline 122. pH of 1% w/v solution was measu red with the help of pH meter and it was observed to be 4.60 at 29 °C.
Executive summary:

The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the test solution was determined with the help of digital pH meter. The mean pH was determined to be 4.60 at 29 °C. This value indicates that the substance is acidic in nature.
