Administrative data
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2006-09-27 to 2007-04-18

Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- 1.7
- Temp.:
- 25 °C
- pH:
- 2.5
- Details on results:
- Mean calibration curve produced was: logPow = 4.55 logk + 3.30. A value of logPow for VRT-126016 of 1.7 was thus obtained.
