Understanding the precise chemical properties and specifications of essential compounds is fundamental for R&D scientists and procurement managers across various industries. Rubidium Chloride (RbCl), identified by CAS number 7791-11-9, is one such compound whose detailed characteristics dictate its suitability for diverse applications. This article outlines the key properties that make RbCl a valuable inorganic salt.

Rubidium Chloride is an inorganic chemical compound with the molecular formula RbCl. It typically presents as a white crystalline powder. Its molecular weight is calculated to be approximately 120.92 g/mol. This relatively simple ionic compound is formed between the alkali metal rubidium and the halogen chlorine.

One of the most significant properties of Rubidium Chloride is its high solubility in water. At 20°C, it exhibits a solubility of around 910 g/L. This high solubility makes it convenient for applications requiring aqueous solutions, such as in chemical synthesis or biological media preparation. It also shows solubility in other polar solvents, though typically to a lesser extent than in water. Its melting point is approximately 718°C, and its boiling point is around 1390°C, indicative of a stable ionic lattice structure.

For industrial and research applications, the purity of Rubidium Chloride is a critical specification. Manufacturers commonly offer RbCl in various purity grades, ranging from standard technical grades to high-purity grades such as 99.9%, 99.99%, or even higher. These specifications are often verified through analytical methods like argentometric titration for chloride content and spectroscopic methods for trace metal impurities (e.g., Li, Na, K, Cs, Al, Ca, Fe, Mg, Si, Pb). Ensuring the correct purity level is vital, especially when using RbCl in sensitive applications like perovskite solar cells or pharmaceutical formulations.

Procurement professionals looking to buy Rubidium Chloride should always consult the supplier's technical data sheets and Certificates of Analysis to confirm that the product meets their specific requirements. Reliable manufacturers, often based in regions with robust chemical production, can provide these critical documents and ensure consistent product quality.

In summary, the chemical properties of Rubidium Chloride – its molecular structure, physical form, solubility, melting/boiling points, and crucially, its purity levels – are all factors that determine its utility. Researchers and manufacturers interested in utilizing this versatile compound should prioritize sourcing from reputable suppliers who detail these specifications accurately.
