- 0.445
- Temp.:
- 37 °C
- pH:
- 3.3
- Remarks on result:
- other: Log Pow = -0.3516
- Details on results:
- Converting the above Pow value into its Log value, the Log Pow of test chemical is -0.3516 at temperature 37°C and pH of 3.30.
- Conclusions:
- The experimental value of octanol water partition co-efficient (log Pow) of test chmical is -0.3516 at temperature 37°C and pH of 3.30.
- Executive summary:
The experimental value of octanol water partition co-efficient (log Pow) of test chemical is -0.3516 at temperature 37°C and pH of 3.30. This value indicates that test chemical is moderately hydrophilic in nature.
