The sodium bromide is an inorganic compound in its dry form a white crystalline powder with a salty and somewhat bitter taste.
The chemical formula for sodium bromide in NaBr.
Sedoneural is a white crystal or white, granular powder having the odour of sulphur dioxide.
Sodium bromide does not occur as natural solid due to its solubility, it is extracted from ocean water along with chlorides, iodides and halites.
Natriumbromide possesses anticonvulsant properties of any bromide salt and one of the most common salts of hydrobromic acid.
Sodium bromide used as a sedative like other bromides.
Bromide salt of sodium used in oil and gas drilling industry is a principal consumer of sodium bromide.

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.
In 1975, bromides were removed from drugs in the U.S. such as Bromo-Seltzer due to toxicity.
Because of its high solubility in water (943.2 g/L or 9.16 mol/L, at 25 °C) sodium bromide is used to prepare 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.
NaBr has a very low toxicity with an oral LD50 estimated at 3.5 g/kg for rats, this is a single-dose value. Bromide ion is a cumulative toxin with a relatively long half life (in excess of a week in humans).

The effective antiepileptic drugs for long-term use /in treating Wolf-Hirschhorn syndrome, a malformation syndrome often with refractory seizures and status epilepticus/ were sodium bromide, followed by clorazepate, and nitrazepam.
Sodium bromide was particularly effective for preventing status epilepticus.
Sodium Bromide is a sedative & hypnotic which is only effective when used over period of time. It is useles as a occasional hypotic.
NaBr is too dangerous for continued use except cautiously for selected cases of grand mal epilepsy in children which do not respond to conventional less toxic agents.
Only high-boiling acid can be used to prepare low-boiling acid.
