EC number: 807-754-7
CAS number: 89929-57-7
Calculation of the Pow: The Pow of the test
substance was calculated to be 1.6 × 10^3 (log Pow 3.2) using the Rekker
Calculation of the pKa: No pKa values for
acidic and basic groups in the molecular structure of the test substance
in the logarithm range of 1 − 14 were calculated.

The equation of the regression line was: log
k’ = 0.349 × log Pow – 0.860 (r = 0.998, n = 12).
In the chromatogram of the test solution,
one test substance peak was observed.
partition coefficient of the test substance was measured, under GLP,
according to the OECD 117 guideline,
The system was calibrated with 6 reference
substances, between log Kow 1.9 and 4.8, and the result for the sample
was interpolated from the linear regression.
The partition coefficient (log Kow) of the
test substance has been determined to be 3.8 (at 35°C, and neutral pH).
The substance has low potential for bioaccumulation, according to CLP
classification criteria for aquatic chronic toxicity (log Kow <4).
It should also be of no concern for PBT assessment.
A reliable experimental study, conducted according to a recognized
OECD/EC method (HPLC) and under GLP, is available. Despite minor
restrictions on accuracy, it is considered as a key study. The result is
retained as key data.
