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.
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.
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.
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.
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.
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.
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.
