Applicant's summary and conclusion

Conclusions:
The pH of 1% w/v aqueous solution of the test item p, p’, p’’-tris (diethyl amino) trityl alcohol (CAS No. 596-49-6) was 7.65 at 24.9°C.
Executive summary:

The pH determination of test item p, p’, p’’-tris (diethyl amino)trityl alcohol (CAS No. 596-49-6) was done following OECD guideline 122 pH of 1% w/v aqueous solution was measured with the help of pH meter/probe and it was observed to be 7.65 at 24.9 °C. Based on the experimental result , p, p’, p’’-tris (diethyl amino) trityl alcohol (CAS No. 596-49-6) was considered to be neutral in nature.
