Description

Application

Rubidium chloride (RbCl) may be used as a non invasive biomarker. RbCl may be used to study the chronotypic effects of Rb in hamsters. A RbCl layer inserted inside an electron transport layer (ETL), tris (8-hydroxyquinoline) aluminum (Alq3) can act as a multilayer organic light-emitting diode (OLED.

What is Rubidium Chloride, Product R2252,soluble in?
This product is soluble in water (100 mg/ml), yielding a clear to slightly hazy, colorless to very faint yellow solution. Also, per the chemicals encyclopedia published by the Royal Society of Chemistry, 13th Edition, 1 gram will dissolve in 90ml of Methanol or 1650ml of Ethanol.
How is Rubidium Chloride, Product R2252, used in the area of Material Science?
Rubidium Chloride has been used to prepare molecular nanowires as potential precursors of nanoscale devices. (Akutagawa, T., et al., Formation of oriented molecular nanowires on mica surface. Proc. Natl. Acad. Sci. USA, 99(8), 5028-5033 (2002).)
Do I need to be aware of anything when handling Rubidium Chloride, Product R2252?
Yes, Rubidium Chloride is hygroscopic and will absorb water. This should be taken into account when handling and storing this compounds. Flushing the head space of the bottle with Nitrogen and storing it in a dessicator will help to keep the material from absorbing moisture.
How is Product R2252, Rubidium Chloride made?
There are many techniques and methods for Rubidium Chloride - here a few: One way to make rubidium chloride is to react the hydroxide with hydrochloric acid. The resulting salt can then be purified by recrystallization.RbOH(aq) + HCl(aq)-> RbCl(aq) + H2O(l)Rubidium(I) bromide can also be made by the neutralization of rubidium(I) carbonate with hydrobromic acid. The resulting salt can then be purified by recrystallization.Rb2(CO3)(aq) + 2HBr(aq)-> 2RbBr(aq) + H2O(l) + CO2(g)While not a normal route of preparation because of the expense, rubidium metal reacts vigorously with all the halogens to form rubidium halides. So, it burns with chlorine, Cl2, to form rubidium(I) chloride, RbCl.2Rb(s) + Cl2(g)-> 2RbCl(s)
