Applicant's summary and conclusion
- Conclusions:
- The water solubility of the substance is <1µg/L.
- Executive summary:
The water solubility of the substance has been determined by UPLC-MS according to OECD guideline 105, EC guideline A.6, and OPPTS 830.7840, and GLP standards.
The UPLC-MS method has been validated within the study report and found to be an acceptable method for water solublity determination.
The water solubility of the substance is <1µg/L at 20°C and a pH of 7.4.
