Description

Magnesium Sulfate Hexahydrate is a high-purity, crystalline inorganic salt essential for numerous industrial and pharmaceutical processes. Its primary value lies in providing a bioavailable source of magnesium and sulfate ions, which are critical for biochemical functions and chemical synthesis. This compound is vital for manufacturers in the pharmaceutical, agriculture, nutraceutical, and chemical industries seeking a reliable and consistent raw material. We supply Magnesium Sulfate Hexahydrate CAS NO 17830-18-1 to meet the stringent quality requirements of global B2B customers.

Application

Magnesium Sulfate Hexahydrate serves as a versatile intermediate and active ingredient across multiple sectors. Key commercial applications include:

• Pharmaceutical Manufacturing: Used as an electrolyte replenisher in intravenous (IV) solutions and a laxative agent in oral preparations.
• Agriculture & Horticulture: Applied as a highly soluble magnesium fertilizer to correct soil deficiencies and prevent chlorosis in crops.
• Nutraceutical & Food Grade Supplements: Serves as a magnesium source in dietary supplements and as a firming agent (E518) in food processing.
• Industrial Process Chemistry: Acts as a drying agent, a coagulant in the production of textiles and paper, and a precursor for other magnesium compounds.
• Laboratory & Research: Employed as a buffer component and magnesium ion source in molecular biology and biochemical assays.
• Water Treatment: Utilized in wastewater treatment processes to facilitate settling and removal of contaminants.
