Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ammonium hydrogencarbonate does not hydrolyze nor is there evidence for photodegradation. As ammonium bicarbonate is an inorganic compound which rapidly dissociates in water, some physico-chemical endpoints (Henry’s law constant, partition coefficient) and biodegradation are not easily applicable. In general, fate and behavior of ammonium bicarbonate are closely related to nitrogen and carbon cycles in air and water. Ammonium bicarbonate rapidly dissociates in the environment to yield ammonium ion (NH4 +), bicarbonate ion (HCO3 -) and un-ionized ammonia (NH3). Based on the high water solubility and the ionic nature, ammonium bicarbonate is not expected to adsorb or bioaccumulate to a significant extent. Due to the salt-character of the substance the calculation of a fugacity model is not appropriate. Based on the physico-chemical properties of ammonium bicarbonate, water is expected to be the main target compartment. Based on the high water solubility a low geoaccumulation potential and high mobility in soil is to be expected. However, due to ion-ion interactions it is to be expected that mobility in soil is significantly reduced.
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.
