Description
Magnesium oxide is an inorganic salt supplied at a minimum purity of 98 % in Ph.Eur. and USP quality, presented in granulated form for convenient handling. It is identified by CAS number 1309-48-4 and EG number 215-171-9, with the empirical formula MgO, a molar mass of 40,30 g/mol, a density of 3,58 g/cm³, and a boiling point of 3600 °C. supports pharmaceutical reference work, inorganic synthesis, buffer and media preparation, and analytical procedures that specify pharmacopoeial magnesium oxide. Granulation improves flow and weighing compared with fine powders while retaining the chemical identity required by Ph.Eur. and USP monographs. Offered by manufacturer Carl ROTH within salts in pharmacopoeia quality, this material suits quality-control, formulation, and research laboratories that need documented grade and clear physicochemical data. Density and thermal figures aid process design and safety evaluation, and the plastic packaging is practical for routine bench and store use without compromising product integrity under normal laboratory conditions.

Questions about Magnesium oxide, min. 98 %, Ph.Eur., USP, granulated, 500 g, plastic
What is this article?
Magnesium oxide, min. 98 %, Ph.Eur., USP, granulated, 500 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.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Metals, elements & oxides. The catalogue is Lab chemicals.
Shelves beside this one are Inorganic salts and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
