Applicant's summary and conclusion

Conclusions:
The pH determination of test item Tripiperazine dicitrate (CAS No. 144-29-6) 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 5.60 at 26.5 °C.
Executive summary:

The pH determination of test item Tripiperazine dicitrate(CAS No. 144-29-6) was done as per the test guideline OECD 122. The pH of the test solution was determined with the help of pH probe. The measurement interface was Micro Lab FS-524; software version 6.2 8b. The pH was found to be 5.60 at 26.5°C.
