Description
Application
Potassium bromide has been used in the sample preparation for fourier transform infrared spectroscopy (FT-IR). It has also been used as a supplement in Wilbrink Selective Davis (WSD) medium.
May be used for removal of peripheral membrane proteins.
Biochem/physiol Actions
Potassium bromide (KBr) is used as an anticonvulsant and sedative. KBr is used for optical windows and prisms. KBr 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.
