Introduction

It tastes bitter. Very high moisture absorption. Easily soluble in water and ethanol, the aqueous solution is neutral.

Application
Magnesium chloride (CAS 7786-30-3) is a highly soluble inorganic salt widely used as a deicing agent, dust suppressant, and coagulant. In cold regions, it effectively lowers the freezing point of water, often outperforming sodium chloride for road and runway deicing while being less corrosive to concrete and metal. As a coagulant, it is used in wastewater treatment and tofu production (as a firming agent, nigari). In the chemical industry, MgCl₂ serves as a precursor for magnesium metal, magnesium oxide, and other magnesium compounds. It is also employed as a catalyst support in Ziegler-Natta polymerization for polyolefin production. In construction, it acts as a hardening accelerator in magnesium oxychloride cement. Additionally, it finds use as a de-icer for coal, a stabilizer in drilling fluids, an electrolyte in batteries, and a nutrient supplement in agriculture and animal feed. High-purity grades are used in pharmaceutical formulations. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity magnesium chloride with flexible scaling from R&D to commercial tons.
