Chemical Name: MAGNESIUM CHLORIDE, 98%
CAS No.: [7786-30-3]

  • Description
    Magnesium chloride, also known as halite, has the chemical formula MgCl₂. The most common form is hexahydrate magnesium chloride, also known as hydrated magnesium chloride, with the chemical formula MgCl₂·6H₂O and a molecular weight of 203.30. The crystals are colourless, hygroscopic monoclinic crystals with a bitter-salty taste.

  • Product Characteristics
    ● Magnesium chloride is a white, lustrous hexagonal crystal that is highly hygroscopic. It is odourless and has a bitter taste. Relative molecular mass: 95.22. Density: 2.32 g/cm³. Melting point: 714°C. Boiling point: 1412°C. Sparingly soluble in acetone, soluble in water, ethanol, methanol, and pyridine. It deliquesces and emits smoke in moist air, sublimates when heated to white heat in a hydrogen gas stream, and is highly soluble in water while releasing heat vigorously.

  • Applications

    Pharmaceutical & Healthcare

    Drug Formulations: Used in magnesium supplements, antacids, and injectables (GMP-compliant production)

    Medical Dressings: Hemostatic agent or wound care component

    Food Industry

    Food Additive (E511): Tofu coagulant and nutritional fortifier

    Dietary Supplements: Prevents magnesium deficiency

    Industrial Uses

    De-icing Agent: Eco-friendly alternative to sodium chloride with lower corrosivity

    Chemical Raw Material: For magnesium metal production, catalysts, and flame retardants

    Construction: Key component in magnesium oxide cement (MgO boards)

    Agriculture & Environment

    Animal Feed Additive: Promotes skeletal development in livestock

    Wastewater Treatment: Acts as flocculant or pH regulator
