- Specific details on test material used for the study:
- Batch/Lot number: 472782
Description: White to off-white to slightly yellow solid
Purity: 99.8% - Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- 2.15
- Temp.:
- 25 °C
- Remarks on result:
- other: pH unknown
- Details on results:
- The three independent calibration series and three test item samples were measured. The partition coefficient Pow was determined based on a calibration curve using the seven reference substances. Under the above detailed chromatographic conditions, the test item (Peak I) had a retention time at 3.12 minutes. Using the linearity equation, the estimated partition coefficient of the test item is LogPow 2.15 ± 0.004 (with 95% confidence interval).
- Conclusions:
- The LogPow is estimated as 2.15 using HPLC method.
