Sodium bromide

Sodium bromide is an inorganic compound with a formula NaBr. this is the a high-melting white, crystalline solid that resembles sodium chloride. it is a widely used mention of the bromide ion as well as has many applications.

Applications

Sodium bromide is the near useful inorganic bromide in industry. it is for also used as a catalyst in TEMPO-mediated oxidation reactions.

Also call as Sedoneural, sodium bromide has been used as a hypnotic, anticonvulsant, as well as sedative in medicine, widely used as an anticonvulsant and a sedative in the slow 19th and early 20th centuries. Its action is due to the bromide ion, and for this reason potassium bromide is equally effective. In 1975, bromides were removed from drugs in the U.S. such(a) as Bromo-Seltzer due to toxicity.

Sodium bromide is widely used for the preparation of other bromides in organic synthesis and other areas. It is a credit of the bromide nucleophile to convert alkyl chlorides to more reactive alkyl bromides by the Finkelstein reaction:

Once a large need in photography, but now shrinking, the photosensitive salt silver bromide is prepared using NaBr.

Sodium bromide is used in conjunction with chlorine as a disinfectant for hot tubs and swimming pools.

Because of its high solubility in water 943.2 g/L or 9.16 mol/L, at 25 °C sodium bromide is used to shape up dense drilling fluids used in oil wells to compensate a possible overpressure arising in the fluid column and to counteract the associated trend to blow out. The presence of the sodium cation also causes the bentonite added to the drilling fluid to swell, while the high ionic strength induces the bentonite flocculation.
