Description of key information

Additional information

Abiotic degradation is not a relevant pathway for 4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) (CAS No. 107934-68-9). Indirect photolysis is not to be expected, since the substance is not likely to be present in the atmosphere due to its low vapour pressure (< 1 Pa). Abiotic hydrolysis is not relevant, since the substance is insoluble in water (<0.052 mg/L in aqua dest, approx. 1-2 µg/L in Daphnia test medium). Additionally, the substance does not contain hydrolysable groups.
