Magnesium dichloride CAS：7786-30-3
Anhydrous magnesium chloride is produced through dehydration or specific processes (such as thermal decomposition of magnesium ammonium chloride compound salts, or molten electrolysis of magnesium chloride, etc.), removing the crystalline water and some impurities (such as sulfate, boron, etc.) that were carried along with the water.
This makes it a key raw material for the production of high-purity magnesium metal (through molten salt electrolysis). Impurities can seriously affect the efficiency of the electrolysis and the purity of the magnesium.
High water absorption: Magnesium chloride without water is an efficient desiccant and moisture absorber, suitable for applications requiring deep drying.
As a catalyst or precursor: In organic chemistry (such as the Ziegler-Natta catalyst), the absence of water is essential because water would poison the catalyst.
Preparation of other high-purity magnesium compounds: This is an ideal starting point for the production of high-performance materials such as high-purity magnesium oxide and magnesium hydroxide.
Anhydrous magnesium chloride (Magnesium dichloride) is a biochemical reagent that can be used as a biological material or an organic compound in life science-related research.

Indication of immediate medical attention and special treatment needed, if necessary
Absorption, Distribution and Excretion
Three mature ewes each received by intrarumenal infusion a supplement of 0, 1, 2 and 3 g Mg/d in sequence over four 10-day periods. Net Mg absorption distal to the pylorus took place down its electrochemical gradient, although the quantity absorbed remained small during the control and first infusion periods. The bulk of Mg absorption occurred before the pylorus and, during the control and first infusion periods, took place against its electrochemical gradient. The net Mg absorption proximal to the pylorus rose with declining efficiency as Mg intake was increased. It is suggested that saturation of the absorption process at this site was occurring.
