Sodium Bromide Description:

Sodium bromide is White crystal powder. Mainly used as oil well completion liquid, work over fluid, also employed in the preparation of photographic emulsions and developers. In pharmaceutical preparations, as a wood preservative, for water treatment, as a flame retardant additive.

 

Sodium Bromide Usage:

Medicine

Also known as Sedoneural, sodium bromide has been used as a hypnotic, anticonvulsant, and sedative in medicine, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries. Its action is due to the bromide ion, and for this reason potassium bromide is equally effective.

 

Preparation of other bromine compounds

 

Sodium bromide is widely used for the preparation of other bromides in organic synthesis and other areas.

 

Disinfectant

NaBr is used in conjunction with chlorine as a disinfectant for swimming pools.

 

Petroleum industry

Sodium bromide is used to prepare dense fluids used in oil wells.
