General description
Potassium bromide, a water-soluble inorganic salt, is redox reagent.
Application
Potassium bromide may be used along with:
- Cerium(IV) ammonium nitrate (CAN) for synthesizing dibromides via alkene bromination.
- Sodium perborate for synthesizing brominated anilines via oxidative bromination of unprotected aromatic amines.
- Hydrochloric acid and hydrogen peroxide for the bromination of active methylene and methyne compounds with high chemoselectivity.
May be used for removal of peripheral membrane proteins.
Suitable for use with FT-IR spectrometers

The purpose of this study is to show how disaccharides differ in their ability to protect lyophilized β-galactosidase from enzymatic activity loss and secondary structure changes during storage. β-galactosidase was lyophilized with trehalose, sucrose, cellobiose or melibiose at 2:1, 20:1
