Description

Magnesium Sulfate is an essential inorganic salt widely recognized for its versatility and critical role in numerous industrial and biological processes. Its high solubility and bioavailability make it a fundamental source of magnesium and sulfur ions, addressing key requirements in manufacturing, agriculture, and healthcare. This compound is indispensable for industries including pharmaceuticals, agriculture as a fertilizer and soil amendment, food processing, chemical synthesis, and water treatment.

Application

• Agriculture: Used as a highly soluble magnesium fertilizer to correct soil deficiencies and prevent chlorosis in crops; also employed in horticulture and hydroponic systems.
• Pharmaceuticals: Serves as an active pharmaceutical ingredient (API) in laxatives and electrolyte replenishers, and as a mineral supplement in vitamin formulations.
• Food Industry: Functions as a firming agent, flavor enhancer, and processing aid (FCC Grade); used in brewing, tofu production, and as a nutrient source in food fortification.
• Chemical Manufacturing: Acts as a drying agent, a precursor in chemical synthesis, and a coagulant in the production of various materials.
• Water Treatment: Utilized in wastewater treatment processes to remove contaminants and control alkalinity.
• Industrial Processes: Applied in textiles (dyeing and finishing), leather tanning, ceramics, and as a component in fireproofing materials.
• Laboratory & Research: Used as a reagent in molecular biology (e.g., cell culture media) and analytical chemistry.

Quality Control

Our Magnesium Sulfate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Products are available in various grades, including Technical, USP, and FCC, each meeting the relevant purity and safety specifications. Comprehensive testing is performed, and a Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or dissolution.
