Ruthenium Bromide is a highly water soluble crystalline Ruthenium source for uses compatible with Bromides and lower (acidic) pH. Metallic Bromides are marketed under the trade name AE Bromides™. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding carbon disulfide (CS2) and chlorine. Ruthenium Bromide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Ruthenium is a Block D, Group 8, Period 5 element. The number of electrons in each of Ruthenium's shells is 2, 8, 18, 15, 1 and its electronic configuration is [Kr] 4d7 5s1. In its elemental form ruthenium's CAS number is 7440-18-8. The ruthenium atom has a radius of 132.5.pm and it's Van der Waals radius is 200.pm. Ruthenium tetroxide (RuO4) is very toxic and Ruthenium in its elemental form is considered carcinogen. Ruthenium is member of the platinum group of metals. It is one of the most effective hardeners for platinum and palladium , and is alloyed with these metals to make electrical contacts for severe wear resistanant electronics and laboratory equipment. The corrosion resistance of titanium is improved a hundredfold by addition of 0.1% ruthenium. It is also a versatile catalyst. Hydrogensulfide can be split catalytically by light using an aqueous suspension of cadmiumsulfide particles loaded with ruthenium dioxide. It is also believed to have pharmacological applications. Ruthenium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Ruthenium was first discovered by Karl Klaus in 1844. The name Ruthenium, originates from the Latin word 'Ruthenia' meaning Russia. See Ruthenium research below.
