De-icing and Dust Control: Anhydrous Magnesium Chloride is widely used for road de-icing in winter and as a dust suppressant in construction or mining operations. It is an eco-friendly alternative to other de-icing agents such as sodium chloride (salt) and calcium chloride.
Water Treatment: It plays a significant role in water purification processes, including the removal of impurities and softening of hard water.
Magnesium Production: As a key precursor in the production of metallic magnesium, Anhydrous Magnesium Chloride is used in the extraction process through electrolysis.
Pharmaceutical and Nutritional Supplements: It is used in the preparation of magnesium-based supplements and in the pharmaceutical industry as a magnesium source for various treatments.
Industrial Uses: It serves as an essential material in the manufacturing of textiles, paper, and other chemicals. It is also employed in fireproofing and heat-resistant products.
High Efficiency: Anhydrous Magnesium Chloride’s moisture-absorbing properties make it highly effective in controlling dust and reducing road ice, especially in areas with freezing conditions.
Cost-effective: Compared to other de-icing agents, it offers a more affordable solution for road maintenance and industrial applications.
Environmentally Friendly: It is less corrosive than sodium chloride, making it safer for the environment and reducing damage to vehicles, infrastructure, and vegetation.
Versatility: Its diverse range of uses across industries like water treatment, chemical manufacturing, and pharmaceuticals makes it a highly versatile compound.
This is the most common selection question for procurement buyers. Here is a direct comparison:
| Criterion | Anhydrous MgCl₂ (CAS 7786-30-3) | Hexahydrate MgCl₂ (CAS 7791-18-6) |
|---|---|---|
| Water content | None | ~53% water by mass |
| Elemental Mg content | ~25.5% | ~11.8% |
| Best for | Grignard synthesis, anhydrous catalysis, desiccants, magnesium metal production | De-icing, dust suppression, tofu coagulant, aquaculture |
| Handling | Hygroscopic; requires sealed, dry conditions | Less sensitive; easier ambient storage |
| Cost per unit Mg | Higher unit price, higher active content | Lower unit price, higher freight per active kg |
| Available grades | Industrial, lab (≥98%), high-purity (≥99%) | Food, technical, industrial, FCC/USP |
Application

Q: Is your anhydrous magnesium chloride suitable for Grignard reactions?
A: Yes. Our ≥98.5% lab grade and ≥99.0% high-purity grade are both suitable for Grignard and other moisture-sensitive synthetic applications. We recommend requesting a sample for your specific protocol validation.
Q: What is the difference between your industrial grade and high-purity grade?
A: Industrial grade (≥98.0%) is manufactured for applications like catalyst support, refractory, and oil field brines where trace impurities are tolerable. High-purity grade (≥99.0%) undergoes additional purification steps to minimize heavy metals and alkali chloride content, making it suitable for battery materials, electronics, and precision synthesis.
Q: Can you provide an anhydrous certificate confirming water content?
A: Yes. Our COA includes Karl Fischer titration data for moisture content (typically ≤0.5%) on every lot.
Q: What is the minimum order for a trial sample?
A: We offer 500 g to 5 kg laboratory trial samples. Please contact us to arrange sample shipment with full documentation.
Q: Do you supply under long-term supply agreements?
A: Yes. We welcome annual frame agreements with scheduled deliveries. Volume pricing and locked-in specifications are available for qualifying customers.
