Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Anilines (Aromatic Amines):

--------------------------

For Fish Acute Toxicity Values: 2,3,5,6-Tetrachloroaniline is 19 times

more toxic than predicted by this SAR. Tetrabromoaniline may be more toxic

than predicted by this SAR as well.

For Daphnid and Green Algae Toxicity Values: Tetrachloro- and tetrabrom-

aniline may be 20 times toxic than predicted by this SAR.

N-Substituted anilines are less toxic than predicted by these SARs;

for these compounds, Neutral Organic SARs are used.
