Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Photolysis is defined as the cleavage of a chemical bond upon absorption of light energy.
Pure ammonium bromide is a white (i.e. colourless) crystalline substance
This inorganic compound will dissociate in water to the ammonium cation and the bromide anion.
NH4Br -> NH4+ + Br-
Aqueous solutions of ammonium bromide do not exhibit any absorption in the visible light spectrum
As neither pure ammonium bromide nor aqueous solutions of ammonium bromide exhibit any absorption in the visible spectrum of light, photolysis will not take place.
Key value for chemical safety assessment

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.
