Description

General description

Potassium bromide (KBr) is an alkaline-earth chloride. Density, viscosity and electrolytic conductivity of concentrated aqueous solutions of alkaline-earth chlorides [KBr, LaCl3, Na2SO4, NaBr, KNO3 and Cd(NO3)2] have been evaluated.

Application

Potassium bromide may be employed in the following studies:
• Spectrophotometric determination of aromatic amino compounds.
• Preparation of AgBr nanoparticles (NPs).
• In combination with cerium(IV) ammonium nitrate (CAN), it has been employed for the bromination of alkenes.
• As an oxidant for the selective monobromination of various deactivated anilines.
• Preparation of sample pellets for IR spectroscopic investigations.

May be used for removal of peripheral membrane proteins.
