Description
Selenium(IV) oxide is a high-purity inorganic oxide offered as ROTI®METIC 99,999 % (5N) material for laboratory chemistry and materials-related applications. It is identified by CAS number 7446-08-4, empirical formula SeO₂ and molar mass 110,96 g/mol, with a density of 3,95 g/cm³. These specifications enable accurate dosing and documentation when selenium dioxide of elevated purity is required. Supplied as 10 g in glass, the pack size suits research, synthesis support and specialty reagent use. ROTI®METIC 5N selenium(IV) oxide from manufacturer Carl ROTH addresses workflows that call for tightly controlled SeO₂ quality, including inorganic preparations and analytical contexts. EG number 231-194-7 and UN number 3283 complete key identity and classification data for laboratory handling and inventory records. With defined composition, high stated purity and a practical glass unit, this selenium(IV) oxide grade helps maintain consistent experimental inputs. It fits chemical portfolios covering high-purity oxides and selenium compounds, giving users a clearly characterised SeO₂ source for controlled laboratory and development work.

Questions about Selenium(IV) oxide, ROTI®METIC 99,999 % (5N), 10 g, glass
What is this article?
Selenium(IV) oxide, ROTI®METIC 99,999 % (5N), 10 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Metals, elements & oxides, inside Inorganic chemicals, in Lab chemicals.
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.
