Additional information

Hydrolysis


The substance is not expected to significantly hydrolyze at environmental conditions.


The only group possibly susceptible to hydrolysis is the amide group which has half-lives measured in centuries at pH 7 (Mabey and Mill 1978). Moreover the molecule is fully conjugated and therefore a hydrolytically sensitive amide group is not present in the molecule anymore.


 


Biodegradation


The substance is expected to be persistent or even very persistent in the environment. It is a pigment which are generally not biodegradable.


 


Adsorption/Desorption


Due to the low logKow (<<3) the substance is not expected to have any adsorption potential.
