EC number: 249-200-1 | CAS number: 28754-28-1
The program KOWWIN (part of EPI Suite) was used for calculating the log POW of the test item. The calculated value was 4.8.
Therefore according to the guidelines the partition coefficient n-octanol/water of the test item at room temperature was determined by the HPLC method.
The results from the HPLC method are summarized in Table2 to Table6.

2)OECD guideline 117, adopted 2004
Parameters: a = 2.7880
b = 2.746
Table6: log POW of the test item – 2nd injection
The partition coefficient POW of the test item was determined to be:
log POW= 4.9
The partition coefficient n-octanol/water of the test itemDisperse Yellow 184.1was determined according to the HPLC method.
It was found to be:
log POW = 4.9
