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

Based on HF / KF data in one hand and NH4Cl data in the other hand, NH4F is assumed to be highly reactive. Once released into the environment, it is unlikely to remain in its original form for any significant length of time.

Ammonium fluoride will rapidly dissociate in aqueous conditions at an environmentally relevant pH into 2 types of compounds:

- Ammonium (NH3, NH4+) which will be rapidly mineralized by bacteria into nitrite compounds, and

- Fluoride ions which will further be transformed in air, water, sediment and soil to form various inorganic fluoride salts and organic complexes.
