Description

Magnesium Sulfate Anhydrous is a high-purity, water-free inorganic salt essential for numerous industrial and technical processes. Its primary value lies in its role as a versatile source of magnesium and sulfate ions, critical for chemical synthesis, nutrient fortification, and water treatment. This product is particularly vital for manufacturers in the pharmaceutical, agricultural, and chemical industries who require a consistent, high-quality reagent free from water of crystallization for precise formulation control.

Application

• Pharmaceutical Manufacturing: Used as an excipient in tablet formulations and as a magnesium source in intravenous solutions and nutritional supplements.
• Agricultural & Horticultural Solutions: Serves as a key component in magnesium-deficient fertilizer blends and soil amendments to correct nutrient imbalances.
• Industrial Chemical Synthesis: Acts as a drying agent, a catalyst support, and a precursor in the production of other magnesium compounds.
• Laboratory & Analytical Reagent: Employed in molecular biology (e.g., PCR buffer component) and as a standard in various analytical chemistry procedures.
• Water Treatment Processes: Utilized in wastewater treatment for nutrient removal and in the production of specialty chemicals for boiler water conditioning.
• Food Processing (Technical Grade): Used in brewing as a brewing salt and in tofu production as a coagulant, where specified food-grade standards are met.

Quality Control

Our Magnesium Sulfate Anhydrous is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and performance. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP, BP) or tailored industrial specifications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
