Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water: screening tests

The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10.

The results indicate that Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride is not expected to be readily biodegradable.

 

Biodegradation in water and sediment: simulation tests

Half life period of Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride in water is observed to be 60 days (1.44e+003 hrs.) while in sediment it is 54.1666 days (1.3e+004 hrs). Based on these half life values of Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride, it is concluded that the chemical is not persistent in water and sediment.

 

Biodegradation in soil

EPI Suite has estimated that Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride is expected to be found not predominantly in soil and its not persistence estimate is based on its transformation in this medium. Its half-life in soil, 120 days (2.88e+003 hrs), does exceeds the threshold of 120 days as per Annex XIII of REACH.

Therefore, Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride is estimated to be not persistent in the soil environment.
