Description

 

Potassium bromide is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the United States. Its action is due to the bromide ion. It is presently used as a veterinary drug, as an antiepileptic medication for dogs and cats. Potassium bromide is transparent from the near ultraviolet to long wave infrared wavelengths and it has no significant optical absorption lines in its high transmission region. It is used widely as infrared optical windows and components for general spectroscopy because of its wide spectral range. It is also used as a restrainer in black and white developer formulas. It improves the differentiation between exposed and unexposed crystals of silver halide and thus reduces fog.
