Potassium Bromide (CAS: 7758-02-3) can be used as analytical reagents and developers, but also for the pharmaceutical industry. It can be used as the emulsion reagents for the filmstrip and photo film; used for formulating developer, used as a sedative in medical treatment. In photographic materials, Potassium Bromide is used in the manufacture of photographic film, developer, film thickener, toner and color photo bleach. In medication, it is used as nerve tranquilizers (tribromide). In addition, it is also used for chemical analysis reagents, the transmission of the spectra and infrared ray, for making special soap as well as being used in sculpture, lithography and so on. It can be used for the preforming in the infrared test. Potassium Bromide is used in photography and as a medical sedative. Potassium Bromide is used for optical windows and prisms. Potassium Bromide is transparent in the wide wavelength range from near ultraviolet to long wave infrared. It is employed in the sample preparation for infrared transmission spectra. Potassium Bromide is not in generally strongly reactive. A weak reducing agent, incompatible with oxidizing agents. Also incompatible with salts of mercury and silver. Violent reactions occur with bromine trifluoride. May react with nitrous ether spirit, many alkaloidal salts and starch. May also react with acids . Reacts with concentrated sulfuric acid to generate fumes of hydrogen bromide.
