Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Regarding stability, under the 10-100 tonnes/annum band, data are required for hydrolysis. However, no data on hydrolysis were located for hydrazine mono-nitrate, or for any of the read-across substances i.e. hydrazine, hydrazine sulphate or hydrazine hydrate. However, due to reported rapid degradation of hydrazine it is not considered necessary to further test for the hydrolysis endpoint.
Due to hydrazine mono-nitrate being an inorganic substance (i.e. a chemical compound that does not contain carbon as the principal element, excepting carbonates, cyanides, and cyanates) and in accordance with Column 2 (Specific Rules for Adaptation From Column 1) of Section 9.2.1.1 (Ready Biodegradability) which states that “The study does not need to be conducted if the substance is inorganic” this endpoint has been waived.
No specific adsorption/desorption data were located for hydrazine mono-nitrate or any of the read-across substances i.e. hydrazine, hydrazine sulphate and hydrazine hydrate. However, it is not considered necessary to specifically test for adsorption and desorption of hydrazine mono-nitrate, due to the evidence available indicating that hydrazine rapidly undergoes degradation and has low log Kow and Koc values.
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.
