Description of key information

Based on two different methods, Koc values for diisopropylnaphthalene (DIPN) of 36,108 and 188,973 were calculated.

Key value for chemical safety assessment

Koc at 20 °C:
36 108

Additional information

Based on First Order Molecular Connectivity Index, a log Koc of 4.5576 (Koc = 36,108) was calculated for DIPN indicating low mobility and accumulation in soil.

Alternatively, log Koc was calculated based on log Kow resulting in an even higher Koc value of 188,973 (log Koc 5.2764).
