Description

Magnesium Sulfate Heptahydrate CAS NO 10034-99-8 is a high-purity, crystalline inorganic salt essential for a wide range of industrial, agricultural, and pharmaceutical processes. It serves as a critical source of bioavailable magnesium and sulfate ions, making it indispensable for applications requiring precise nutrient delivery or chemical synthesis. This versatile compound is a key raw material for manufacturers in the fertilizer, animal feed, pharmaceutical, food, and chemical industries.

Application

• Agriculture & Horticulture: A primary ingredient in magnesium-deficient soil fertilizers and a nutrient supplement in hydroponic systems and foliar sprays.
• Animal Nutrition: Used as a magnesium supplement in feed premixes for livestock, poultry, and aquaculture to support metabolic functions and bone health.
• Pharmaceutical Manufacturing: Employed as an active pharmaceutical ingredient (API) in laxatives, electrolyte replenishers, and in the preparation of Epsom salt.
• Food & Beverage Industry: Functions as a firming agent, flavor enhancer, and processing aid (FCC Grade), and as a brewing salt in beer production.
• Industrial & Chemical Processes: Acts as a coagulant in the production of tofu, a drying agent in organic synthesis, and a component in bath salts and cosmetics.
• Water Treatment: Utilized in wastewater treatment processes to facilitate settling and as a nutrient in biological treatment systems.
