Description of key information

Due to the rapid hydrolysis, performing of a study was regarded as useless. However, the QSAR determination of the carbon partition coefficient for 2H-1,3,5-Oxadiazine-2,4(3H)-dione, dihydro-3,5-bis(6-isocyanatohexyl)-6-[(6-isocyanatohexyl)imino]- (CAS 197071-15-1) using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.11 revealed values of 2.525*E+05 L/kg (logKow method) and 1.581*E+07 L/kg (MCI method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.  
The organic carbon partition coefficient (Koc) of the corresponding diamine, 2H-1,3,5-Oxadiazine-2,4(3H)-dione, dihydro-3,5-bis(6-aminohexyl)-6-[(6-aminohexyl)imino]- was predicted using the QSAR calculation of the Estimation Program Interface (EPI) Suite v 4.11. The Koc was estimated to be 944.1 L/kg (logKow method), and 9.928*E+04 L/kg (MCI method). The results relate to the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
