Applicant's summary and conclusion

Conclusions:

The pH of 1% w/v dispersion of the test item Butylhydroxyoxostannane (CAS No2273-43-0) was 6.40 at 27°C.

Executive summary:

The pH determination of test item Butylhydroxyoxostannane (CAS No 2273-43-0) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter. The mean pH was determined to be 6.40 at 27 °C. Hence Butylhydroxyoxostannane was considered to be acidic in nature.
