cas no.: 7647-15-6 molecular formula: nabr
einecs: 231-599-9 molecular weight: 102.89
property:
sodium bromide is a toxic, white, crystalline sodium compound, free from extraneous impurities. It is thoroughly soluble in water and partially soluble in alcohol. Sodium bromide absorbs moisture from its surroundings. It has a saline and a bitter taste. Sodium bomide melts at 758℃. Sodium bromide resembles a lot to sodium chloride.

usage:
sodium bromide is employed in the preparation of photographic emulsions and further in its processing. Sodium bromide acts as a chemical intermediate for the manufacture of various chemicals and bromides. Sodium bromide is used for water clarification. To obtain hbr, nabr is treated with a strong, non-volatile acid. Sodium bromide 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.
