Rubidium chloride is the chemical compound with the formula RbCl.
Every 18 mg of rubidium chloride is equivalent to approximately one banana equivalent dose due to the large fraction (27.8%) of naturally-occurring radioactive isotope rubidium-87.
Rubidium chloride burns with a red-purple flame in a flame.
Rubidium chloride is a white hygroscopic solid, soluble in water.
Rubidium chloride is sold by lab suppliers. Can also be bought online, though it's pricey.

Rubidium chloride, like all alkali salts, has low toxicity, though it may be irritant to eyes, mouth and lungs.
Rubidium chloride has shown antidepressant effects in experimental human studies, in doses ranging from 180 to 720 mg. It purportedly works by elevating dopamine and norepinephrine levels, resulting in a stimulating effect, which would be useful for anergic and apathetic depression.
In closed plastic or glass bottles.
No special disposal is required, though since rubidium is not cheap, it's best to try and recycle the compound as much as possible.
