The pH of 1% w/v aqueousdispersionof the test item 3-(1H-benzimidazol-2-yl)-7-(diethylamino)-2-benzopyrone (CAS No. 27425 -55 -4 ) was determined to be 6.21 at 30°C.

Applicant's summary and conclusion

Conclusions:
The pH determination of test item 3-(1H-benzimidazol-2-yl)-7-(diethylamino)-2-benzopyrone (CAS No. 27425-55-4)was done following OECD guideline 122. pH of 1% w/v aqueous dispersion was measured with the help of pH meter and it was observed to be 6.21 at 30 °C.
Executive summary:

The pH determination of test item 3-(1H-benzimidazol-2-yl)-7-(diethylamino)-2-benzopyrone (CAS No. 27425-55-4) was done as per the test guideline OECD 122. The pH of the test solution was determined with the help of digitalpH meter. The pH of 1% w/v aqueous dispersion was found to be 6.21 at 30 °C indicating near neutral pH.
