Overview
Magnesium dinitrate hexahydrate (CAS 13446-18-9) is an inorganic nitrate salt with strong oxidizing properties and high water solubility. This crystalline compound represents one of the most important magnesium-based oxidizing agents in industrial chemistry. With the molecular formula H12MgN2O12 and a molecular weight of 256.41 g/mol, magnesium dinitrate hexahydrate appears as colorless to white hygroscopic crystals that readily absorb moisture from air. The hexahydrate form is the most stable and commercially available variant, containing six water molecules per formula unit, which significantly influences its handling and storage requirements. As a member of the alkaline earth metal nitrates family, this compound shares chemical similarities with related substances such as barium dinitrate and calcium dichlorate dihydrate, though each exhibits distinct solubility and reactivity profiles. The compound's classification under ADR Class 5.1 indicates its oxidizing nature, requiring careful handling to prevent incompatible material contact that could lead to fire or explosion hazards. Magnesium dinitrate hexahydrate demonstrates excellent water solubility, making it particularly valuable in aqueous applications. Its oxidizing characteristics become pronounced at elevated temperatures, where thermal decomposition releases oxygen and nitrogen oxides. The compound's hygroscopic nature necessitates proper storage in dry conditions to maintain product integrity and prevent caking. Primary industrial applications include its use as an oxidizing agent in pyrotechnic formulations, as a catalyst component in organic synthesis reactions, and as a nitrating agent in specialized chemical processes. The compound also finds application in analytical chemistry and as a precursor for magnesium oxide production through controlled thermal decomposition. OYSI maintains reliable stocks of high-purity magnesium dinitrate hexahydrate to support diverse European industrial requirements across multiple sectors.
