Beschreibung
Magnesium oxide R₁ is a pharmacopoeia-quality reagent corresponding to Reag. Ph. Eur., Chapter 4.1.1, 1049901. The inorganic oxide has the empirical formula MgO, CAS number 1309-48-4, EG number 215-171-9 and a molar mass of 40,30 g/mol. Density is 3,58 g/cm³ and the boiling point is 3600 °C, values that describe this compact magnesium oxide solid for laboratory use. The 100 g plastic pack supports pharmaceutical quality-control and analytical laboratories that maintain European Pharmacopoeia reagents listed under Chapter 4.1.1. Identification as magnesium oxide R₁ against reagent entry 1049901 allows methods to cite a defined Ph. Eur. reagent rather than an unspecified magnesia grade. Physical data from manufacturer Carl ROTH therefore cover molar mass, density and boiling point together with the CAS and EG identifiers. With a density of 3,58 g/cm³, solids handling can be related to mass, while the boiling point of 3600 °C is recorded for this oxide. The material belongs to the Reagents 4.1.1 group used wherever pharmacopoeial monographs call for magnesium oxide R₁. The 100 g plastic presentation is convenient for routine benches and method verification.
