Trimagnesium dicitrate
Product name:Trimagnesium dicitrate
CAS: 3344-18-1
Molecular Formula: C12H10Mg3O14
Molecular Weight: 451.11
Product description:Magnesium citrate is also called magnesium citrate, white or yellowish powder, non-toxic, non-corrosive, and is formed by magnesium carbonate and citric acid. The magnesium content as high as eleven percent, and contains magnesium are easily absorbed by the body, so is an important source of magnesium supplementation.As normal saline laxative. Before doing any operation, will provide the patient with citric acid magnesium, so Yu Qingkong intestines. This is because it have a tendency to absorb organization moisture, injection after intestinal can draw water out side by side a lot of in vitro. In fact, it still can treat constipation and colon cancer, or diseases associated with colorectal cancer. In addition, the effect of magnesium citrate and prevent kidney stones.
