Magnesium Sulfide LAB GRADE 99%

Magnesium sulfide is colorless to brown crystal powder, which is sulfide of magnesium. It is of sodium chloride type structure and the chemical property is similar to other  ionic type sulfide compounds as sodium sulfide, barium sulfide and calcium sulfide. Magnesium metal and pure sulfur are the raw materials.  It dissolve in diluted hydrochloric acid, however MgS crystal react with water slowly.

Vanillin is used as well as ethylvanillin in the food industry. Vanillin can use as a flavoring and is also used in the fragrance industry,in perfumes, and to mask unpleasant odors or tastes in medicines, livestock fodder, and cleaning products.Besides, Vanillin has been used as a chemical intermediate in the production of pharmaceuticals and other fine chemicals. Vanillin can be still used as a general purpose stain for developing thin layer chromatography (TLC) plates to aid in visualizing components of a reaction mixture.
