- Conclusions:
- In the conditions of the test, the chromatograms of SINODOR CQ show 3 peaks with relative peak areas over 1% at average retention times of 5.05 minutes (1.4% relative peak area), corresponding to a partition coefficient (log value) of 3.5; 18.41 minutes (86.5 % relative peak area), corresponding to a partition coefficient (log value) of 6.0 and 27.92 minutes (12.1% relative peak area), corresponding to a partition coefficient (log value) of 6.6.
Therefore:
Partition coefficients n-octanol/water of SINODOR CQ:
log Pow = 3.5; 6.0* and 6.6 *
* Indicatice values, peaks are outside calibration domain. - Executive summary:
The partition coefficient n-octanol/water of Sinodor CQ was determined by the Reverse Phase High Performance Liquid Chromatographic Method according to the OECD guidelines for testing on chemicals, Method No. 117.
The result is:
Partition coefficients n-octanol/water of SINODOR CQ:
log Pow = 3.5; 6.0* and 6.6 *
* Indicatice values, peaks are outside calibration domain.
