Anhydrous magnesium sulfate

Industrial-grade anhydrous magnesium sulphate (CAS No 7487 88 9) is an essential moisture-free inorganic compound engineered for chemical synthesis, industrial drying, agricultural formulations, and process engineering. Produced via precise thermal dehydration and purification protocols, our product offers an exceptionally dry, free-flowing white crystalline powder with an active assay purity ranging from 98.5% to 99.5%.

As premier magnesium sulphate monohydrate suppliers and global chemical exporters, we provide a complete suite of magnesium sulphate compounds—ranging from high-purity CAS No 7487 88 9 anhydrous grades to monohydrate and heptahydrate variants—designed to meet the rigorous standards of global industrial procurement.

Key Technical Specifications & Advantages

  • Chemical Identifiers: CAS No 7487 88 9 | EC No 231-298-2 | Molecular Formula: $\text{MgSO}_4$

  • High Dehydrating Capacity: Acts as a powerful, non-reactive desiccant that rapidly absorbs residual water from solvent streams, gases, and organic phases.

  • Thermal Stability & Low Impurities: Manufactured with strict controls on heavy metals ($\le 10\text{ ppm}$) and iron ($\le 20\text{ ppm}$), preserving process integrity in sensitive chemical reactions.

  • Concentrated Elemental Yield: Delivers a higher ratio of active magnesium per metric ton than hydrated salts, reducing landed transportation costs for bulk processing.

Core B2B Applications Across Industries

  1. Chemical Synthesis & Organic Drying:

    In organic chemistry and pharmaceutical intermediates manufacturing, anhydrous magnesium sulphate serves as a vital laboratory and plant-scale drying agent. Its rapid hydration rate removes water without reacting with organic functional groups or target solvents.

  2. Water-Soluble Agriculture & Fertilizer Formulation:

    While leading magnesium sulphate monohydrate suppliers supply monohydrate grades for granular soil applications, our anhydrous variant provides an instant-release, highly soluble source of magnesium and sulfur for premium fertigation liquids, foliage sprays, and specialty hydroponic mixes.

  3. Pulp, Paper & Textile Processing:

    Used in pulp bleaching as a cellulose protector to prevent fiber degradation during oxygen delignification. In textiles, it acts as a fabric weighting agent and dye-fixing stabilizer.

  4. Building Materials & Construction Chemicals:

    Incorporated into magnesium oxychloride and oxysulfate cement formulations to accelerate setting speed, improve fire resistance, and increase structural hardness in specialty building boards.

Bulk Global Logistics & Supply Chain Reliability

We understand that industrial buyers evaluate chemical suppliers based on material consistency, packaging integrity, and freight reliability:

  • Heavy-Duty Packaging: Available in standard 25 kg PP woven bags with double PE moisture liners, as well as 1000 kg bulk jumbo bags (super sacks) featuring bottom discharge spouts for automated hoppers.

  • Full Compliance & Documentation: Every shipment is accompanied by a Certificate of Analysis (CoA), Safety Data Sheet (SDS/MSDS), REACH compliance documentation, and full batch traceability.

  • Flexible Shipping Terms: We support FOB, CFR, CIF, and DDP terms with quick containerized dispatch directly from major export ports.
