The HPLC estimation method based on soil-adsorption reference data
was used for the determination of the adsorption coefficient (Koc) of
the substance. The study was performed in accordance with OECD 121 and
in compliance with GLP. The mobile phase was 55/45 (v/v) methanol/water
and the wavelength of detection 210 nm. The stationary phase contained
cyanopropyl chains chemically bonded to silica. Formamide was used as
unretained substance. Duplicate injections of reference substances and
test substance. The chromatogram of the test substance showed one test
substance peak. The corresponding log Koc value was calculated from the
regression line to be 4.07 (Koc= 1.2E04).
