Additional information

According to the data generated by using EPI Suite, KOCWIN, the log Koc of quinine is estimated to be 4.07 and the Koc 1.168e+004 L/kg by using the Molecular Connectivity Index and to be 2.41 (log Koc) and 255.3 L/kg (Koc) estimated from the log Kow. We consider that the log Koc is between 2.41 and 4.07.
