EC number: 700-748-4
CAS number: 1226911-69-8
preliminary assessment of the partition coefficient was made based on
the KowWin calculation method (Epiwin v3.10, Copyright©, 1990-2000,
Microsoft Corp William Meylan) using the molecular structure of the test
Pow: 7.76 x 10 3
4.7/1: Retention times of standards
Log10 Pow = slope x Log10 k + intercept
slope = 3.3085
intercept = 2.1794
correlation coefficient (r) = 0.9908
4.7/2: Partition coefficient of sample
(To) Dead time
= Retention time
RT = = Mean retention time
= standard deviation
coefficient of variation
coefficient: 1.32 x 103
partition coefficient of the test substance was measured under GLP
according to the OECD 117/EU A8 guideline, HPLC method.
system was calibrated with 6 reference substances, between logKow 2.1
and 4, and partition coefficient of the test substance was interpolated
from the linear regression.
coefficient (log Kow) of the test substance has been determined to be
3.12 (at 30°C and pH 5.5).
The substance has low potential for bioaccumulation, according to CLP
classification criteria for aquatic chronic toxicity (log Kow <4).
A fully reliable experimental study, conducted according to a recognized
OECD/EC method and under GLP, is available. It is considered as a key
study. The result is retained as key data.
