Description
Selenium pellets in ROTI®METIC 99,999 % (5N) quality provide high-purity elemental selenium for demanding inorganic and materials applications. The product corresponds to CAS number 7782-49-2 and EG number 231-957-4, with the empirical formula Se, a molar mass of 78,96 g/mol, a density of 4,809 g/cm³ and a boiling point of 685 °C. The 5N specification supports use where impurity levels must remain minimal for reproducible experimental outcomes. Offered from manufacturer Carl ROTH under the ROTI®METIC line, these pellets combine clear physical-property data with a practical pack size for research and specialty inorganic chemistry. Documented CAS, EG, density and boiling-point values aid safe handling planning and technical documentation in the laboratory.
This article is part of Metals, elements & oxides, in Inorganic chemicals.

Questions about Selenium pellets, ROTI®METIC 99,999 % (5N), 10 g, plastic
What is this article?
Selenium pellets, ROTI®METIC 99,999 % (5N), 10 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 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.
