CAS NO.14168-73-1
High Purity & Quality
Meets USP/BP/EP/CP standards with ≥99% content, ensuring consistent performance for industrial, agricultural, and pharmaceutical use.
Excellent Water Solubility
Rapidly dissolves in water, making it ideal for liquid formulations, foliar sprays, and water-soluble fertilizer blends.
Rich in Essential Nutrients
Contains 17.21% magnesium and 86% sulfate, both of which are vital nutrients for crops, livestock, and humans.
Stable Physical Properties
White crystalline or powdered form with excellent flowability and low moisture absorption, easy to handle and store.
Multi-Industry Applications
Widely used in agriculture (as Mg & S fertilizer), food/feed (as additive), pharmaceuticals (as magnesium supplement), and chemical manufacturing.
Magnesium Sulfate Monohydrate is a white crystalline or powder-form compound composed of magnesium, sulfur, and one molecule of crystal water. Known for its high purity and solubility, this material is widely used across various industries, including agriculture, pharmaceuticals, feed, food processing, and chemicals. It delivers essential nutrients—magnesium (Mg) and sulfate (SO?)—and plays a critical role in chlorophyll synthesis, enzyme activation, and nutrient absorption in plants and animals.
With its stable composition and compatibility with international pharmacopeia standards (USP/BP/EP/CP), Magnesium Sulfate Monohydrate is an ideal ingredient in formulations requiring a fast-dissolving, bioavailable magnesium source. It is also commonly used in bath salts, concrete accelerators, and electroplating additives.
Agriculture: Water-soluble magnesium and sulfur fertilizer for crops
Pharmaceuticals: Magnesium supplement and excipient in medicines
Food & Feed: Nutritional additive and processing aid
Chemicals: Raw material for magnesium salts, fire retardants, electroplating
Construction: Coagulant in cement and additives for fire-resistant materials
