General description

Rubidium is a highly electropositive alkaline metal that can be obtained as a byproduct of refining lithium from lepidolite. It is used in photomultiplier tubes, laser cooling, atomic clock, photocell, nuclear medicine, and specialty glass.

Application

Rubidium can be used as a starting material to synthesize rubidium hydrazinidoborane (RbN2H3BH3).
It can also be used as a reducing agent to synthesize reduced polycyclic aromatic hydrocarbons.
