Description

Magnesium Chloride Tetrahydrate is a high-purity inorganic salt essential for numerous industrial and technical processes. Its consistent quality and reliable performance make it a critical raw material for sectors requiring precise magnesium and chloride ion sources. This compound is particularly vital for the chemical manufacturing, pharmaceutical, and food processing industries, where it serves as a precursor, catalyst, or nutrient source.

Application

• Chemical Synthesis & Catalysis: Acts as a precursor for producing other magnesium compounds and as a catalyst or co-catalyst in organic synthesis reactions.
• Pharmaceutical & Nutraceutical Manufacturing: Used as a source of bioavailable magnesium in mineral supplements and as an excipient in tablet formulations.
• Food Industry (FCC Grade): Serves as a firming agent, flavor enhancer, and a mineral nutrient in food products and dietary supplements.
• Dust Control & Road Stabilization: Applied as a highly effective hygroscopic agent for suppressing dust on unpaved roads and stabilizing surfaces.
• Water Treatment: Utilized in wastewater treatment processes for phosphate removal and as a magnesium source in certain desalination techniques.
• Laboratory & Research: Employed as a standard or reagent in analytical chemistry, biochemistry, and molecular biology applications.
• Ceramics & Construction Materials: Functions as a setting accelerator and binder in the production of magnesia cement and other specialty construction materials.
• Agricultural Solutions: Used in fertilizers and soil amendments to correct magnesium deficiencies in crops.

Quality Control

Our Magnesium Chloride Tetrahydrate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting results for assay, heavy metals, loss on drying, and other critical parameters are available upon request. We can supply grades compliant with various standards, including Food Chemical Codex (FCC) and technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from incompatible materials such as strong acids and strong bases.
