Description

Magnesium Chloride, Monohydrate is a vital inorganic salt, recognized for its high solubility and essential role as a source of magnesium ions. This compound is critical for industrial and commercial processes where precise magnesium supplementation and chloride chemistry are required. It serves a wide range of sectors, including the manufacture of magnesium metal, dust control, food processing, and as a key intermediate in pharmaceutical and nutraceutical production.

Application

• Magnesium Metal Production: A primary raw material in the electrolytic production of metallic magnesium.
• Dust Control & Road Stabilization: Used as a highly effective, hygroscopic agent for suppressing dust on unpaved roads and stabilizing soil.
• Food Industry: Employed as a firming agent, flavor enhancer, and a source of nutritional magnesium in food-grade (FCC) applications.
• Pharmaceutical & Nutraceutical: Serves as a magnesium source in dietary supplements and active pharmaceutical ingredients (APIs), meeting pharmacopeial standards (USP/EP).
• Chemical Synthesis: Acts as a catalyst or precursor in various organic and inorganic chemical reactions.
• Industrial Processes: Used in textiles, paper manufacturing, and ceramics as a processing aid and fireproofing agent.
• Water Treatment: Functions in wastewater treatment and as a component in certain specialty deicing formulations.

Quality Control

Our Magnesium Chloride, Monohydrate is produced under a stringent quality management system. We offer various grades, including Industrial, Food (FCC), and Pharmaceutical (USP/EP), each with defined specifications for purity, heavy metals, and other critical parameters. Certificates of Analysis (COA) are provided with every shipment to ensure traceability and compliance with your specific 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 liquefaction.
