Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the aquatic compartment to the substance is unlikely

Description of key information

The substance is solely used in pharmaceutical industry as intermediate to synthesize a drug substance. The study does not need to be conducted because no exposure of the environment is expected.

Chemicals with very high logKow values (i.e, >4.5) are of greater concern because they may have the potential to bio-concentrate in living organisms.

The substance has low logKow value (1.2) and is not of greater concern because it has low potential to bio-concentrate in living organisms.

Key value for chemical safety assessment
