EC number: 915-623-1
CAS number: -
According to OECD/EC test guidelines, the adsorption coefficient using the high performance liquid chromatography (HPLC) method has been determined to be a Koc of 30903 (log Koc = 4.49), which is taken for the assessments, as this value is the worst-case value for the compartment water.
In an OECD/EC study, using the high
performance liquid chromatography (HPLC) method, the adsorption
coefficient was determined. In the chromatogram of the test substance
solution, two partly overlapping large peaks were observed which were
considered to derive from the major components in the test substance.
Furthermore three small test substance peaks were observed. These peaks
were considered to derive from minor components in the test substance.
The Koc and log Koc values of the major components in
2-amylanthraquinone and of one minor component with a peak area > 1%
Minor component – peak 1: Koc = 1.5 x 10^3;
log Koc = 3.18
Major component – peak 4: Koc = 3.1 x 10^4;
log Koc = 4.49
Major component – peak 5: Koc = 3.7 x 10^4;
log Koc = 4.57
