EC number: 407-560-9
CAS number: 107934-68-9
The substance is not readily biodegradable
and half-lives are predicted by models to be > 2 months in the water
compartment. Therefore, the substance could be regarded as potentially
The substance demonstrated to be very
bioaccumulable in a fish bioaccumulation test.
Finally the substance is also very toxic for
the reproduction of invertebrates.
Therefore the substance is potentially vPvB
If the substance is released into the
environment it is expected to adsorb to particle matters. It is not
expected to be volatile, nor transported.
However, the conditions of use do not lead
to exposure or releases to the environment.
Based on its physico-chemical properties
4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) (CAS No. 107934-68-9)
will mainly distribute into soil and sediment, where it can be very
persistent (vP) due its poor degradability. A bioconcentration
test according to OECD 305 and GLP was performed with
4,4’-(9H-fluoren-9-ylidene)bis(2-chloroaniline) as test substance. No
steady state was reached within the exposure period. Therefore, no BCFss
could be calculated. The BCFk obtained, before and after lipid
normalisation, with 4,4’-(9H-fluoren-9-ylidene)bis(2-chloroaniline) were
>5000 and therefore the test item is considered to be very
bioaccumulative in fish.
It should be noted, that due to the strictly
self-contained use of the substance, environmental exposure is unlikely.
