Conclusions:
The values of logPow of test item were 0.84 and 0.85 respectively, the average of logPow of test item was 0.84, the Pow value was 6.9.
Executive summary:

The Partition Coefficient (n-octanol/water) of test item was determined compatible with the Principles of OECD Guidelines for Testing of Chemicals No. 117 ‘Partition Coefficient (n-octanol/water): High Performance Liquid Chromatography (HPLC) Method’. Six compounds were selected as reference substances and thelinear regression graph of logk versus logPowof six reference substances was plotted, the regression equation was Y=0.7153x-0.3700 (R=0.9658). Based on the testing results, the Pow of test item was 6.9, logPowwas 0.84.

Description of key information
