Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Summary of degradation
N2O4 is inorganic and hence the ready biodegradation and hydrolysis tests are not relevant.
Volatilisation
Data on volatilisation are not available for the substance as there is no suitable test method or calculation method for a gas.
Distribution modelling
No distribution modelling data exist.
Summary of environmental distribution
An adsorption / desorption study has not been conducted on the substance as it is not possible due to the physical nature of the substance.
Summary and discussion of bioaccumulation
No experimental data on bioaccumulation exist. The data are not required as the hazard and risk assessment performed during the chemical safety assessment concludes that the substance is not classified as bioaccumlative and is of no immediate concern to the environment.
Secondary poisoning
Bioaccumulation of N2O4 is not expected to occur. Hence no secondary poisoning risk exists.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
