Applicant's summary and conclusion
- Conclusions:
- The pH of 1% w/v dispersion of the test item 3,5-diaminobenzoic acid (CAS No535-87-5)was 3.97 at 27.4 °C.
- Executive summary:
The pH determination of test item 3,5-diaminobenzoic acid (CAS No 535-87-5) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter and it was observed to be 3.97 at 27.4 °C. Based on the value, 3,5-diaminobenzoic acid was considered to be acidic in nature.
