Magnesium Sulfate

Brief Introduction
Molecular Formula MgSO4·nH2O (n=0, 1, 2, 3, 4, 5, 6, 7)
Molecular Weight 120.37+18n (n= 0, 1, 2, 3, 4, 5, 6, 7)
CAS No. 10034-99-8 (MgSO4·7H2O)
7487-88-9 (MgSO4 )

Magnesium is the core element of chlorophyll, and it is absolutely necessary during photosynthesis. The magnesium element functions as the activator of numerous enzymes. It can facilitate the carbohydrate metabolism, phosphate conversion, nucleic-acid synthesis, and some others. Furthermore, magnesium acts as the component of polysomes to participate in the synthesis of proteins. It can be also considered as the transmission media of genes, because it is the constituent of some genes.

Magnesium sulfate is colorless, columnar or acicular fine crystal. It has a salty and bitter taste, and it is odorless. Its density is 2.65g/cm3. This substance shows high stability in humid air at below 48 degrees Celsius. It can be easily weathered in warm air. Additionally, the substance is easily soluble in water (119.8%, 20℃) and glycerol. It is neutral in aqueous solutions, and slightly soluble in ethanol.

Magnesium sulfate can be applied in pharmaceuticals, food, feed supplement, fermentation, engineering plastics, agricultural fertilizers, daily-use chemical industry, and other fields.

Storage and Transportation
Magnesium sulfate ought to be stored in a dry, ventilated and clean warehouse. It can guard against rain and moisture. In addition, it should be isolated from toxic substances.
