CAS number: 90411-76-0
Biodegradation in water:
The substance is considered to be "Not Inherently Biodegradable". As
only 30% of the substance are degraded in the inherent test study design
a "ready biodegradability" of the substance can be excluded.
Within 28 days a degradation rate of 30 % was determined in a study for
the inherent biodegradability of the substance. The substance is
considered to be "Not Inherently Biodegradable". As only 30% of the
substance are degraded in the inherent test study design a "ready
biodegradability" of the substance can be excluded.
Biodegradation in water and sediment: simulation tests
Applying the EAWAG-BBD Pathway Prediction System (PPS) to the molecule
“dihydro-5,7,12,14-tetraazapentacene, diphenylated, monosulfonated”
yields valuable information about the putative environmental fate of the
substance. From the vast amount of possible biotransformation processes
not a single one could be found, which can be considered as very likely
to occur. However, this pathway only affects the phenylic moiety of the
molecule, while the rest of the molecule does not undergo any
further structural changes. Thus, the model does not predict a
significant potential for biodegradation. Instead, only minor changes of
the molecular structure, limited to the phenylic moiety, can be
expected. The arising transformation products are therefore
structurally very similar to the initial educt.
It has to be noted that the investigated molecule acts only as a
representative candidate for the registered substance. Taking this into
account the obtained model data strongly point at a low potential for
biodegradation for the representative molecule
“dihydro-5,7,12,14-tetraazapentacene, diphenylated, monosulfonated” and
as a consequence also for the registered substance “Hydrochloric acid,
reaction products with aniline and nitrobenzene, sulfonated, sodium
salts” CAS no.: 90411-76-0”.
