Usage:
Sodium Bromide is employed in the preparation of photographic emulsions and further in its processing. Sodium Bromide act as a chemical intermediate for the manufacture of various chemicals and bromides. Sodium Bromide is used for water clarification. Pharmaceutical grade is used in medicine as sedatives. To obtain HBr, NaBr is treated with a strong, non-volatile acid. It is used for water clarification and a flame retardant. Sodium Bromide is widely used in organic synthesis, as a nucleophile to convert organochlorine compounds to organobromine derivatives, which are more useful reactives.

Package:
Sodium Bromide is packed in 25kg/PP woven bag with PE liner inside.
