Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In a GLP study according to OECD 201, the growth inhibition of the reaction product of 2,3-dinitrotoluene and 2,6-Dinitrotoluene and hydrogen to unicellular green algae (Desmodesmus subspicatus) was tested. The test concentrations were analytically verified. They remained within 20% of the nominal values, therefore the effect values are given based on nominal concentrations. Based on growth rate inhibition, the 72 -h ErC50 is greater than 220 mg/L. The 72 -h ErC10 was determined to be 75.6 mg/L (BASF SE, 2011; Project No. 60E0117/10E119).
