Beschreibung
Cobalt(II) chloride hexahydrate is an extra-pure inorganic salt of minimum 98 % purity, with CAS number 7791-13-1 and empirical formula CoCl₂ · 6 H₂O. It has a molar mass of 237,93 g/mol, a density of 1,92 g/cm³, and a boiling point of 1049 °C, supporting accurate preparation of cobalt-containing solutions and solid-state work. This variant is Cobalt(II) chloride hexahydrate is widely used as a cobalt source in inorganic synthesis, coordination chemistry, indicator and humidity-sensitive systems, and materials research. The extra-pure grade suits applications that require a defined minimum assay without unnecessary complexity. Product from manufacturer Carl ROTH is identified by EG number 616-574-6 and UN number 3077. Clear molar mass and density values aid reproducible weighing and solution make-up. Laboratories employ this hydrate for preparing standard solutions, doping experiments, and cobalt salt transformations. Plastic packaging allows practical storage and handling of the crystalline reagent in everyday laboratory use.

Questions about Cobalt(II) chloride hexahydrate, min. 98 %, extra pure, 50 g, plastic
What is this article?
Cobalt(II) chloride hexahydrate, min. 98 %, extra pure, 50 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Metals, elements & oxides, inside Inorganic chemicals, in Labor- und Industriechemikalien.
Metals, elements and oxides are the element itself or its oxide, sold as powder, shot, foil or wire. Purity and particle size are both the specification. A 99 percent powder and a 99.999 percent shot of the same element are different articles. Many are reactive to air or to water.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
