Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In the aqueous environment, hydroxylammonium nitrate is expected to dissociate to [NH3OH]+and [NO3]2-. The hydroxyl-ammonium ion is rapidly converted to hydroxylamine (free base). Hydroxylamine (free base) is stable in pure water in the absence of oxygen. However, the substance is a strong reduction agent and in the presence of oxygen, metals and other ions is rapidly transformed by abiotic processes (Hollemann-Wiberg, 1995). The ultimate transformation products are ammonium, nitrogen and N2O. The reaction is dependent on the pH. The more basic the environment, the more rapid the transformation.

On this basis it is appropriate to read across from relevant results for hydroxylamine, hydroxylammonium chloride and hydroxylammonium sulphate.
