Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Graphite, hexagonal boron nitride, molybdenum disulfide and tungsten disulfide are examples of solid lubricants. Thiram is the simplest thiuram disulfide and the oxidized dimer of dimethyldithiocarbamate. The compound adopts a hexagonal crystalline structure similar to molybdenum disulfide. It thermally decomposes into disulfide and elemental sulfur. White phosphorus is insoluble in water but soluble in carbon disulfide. Iridium also reacts directly with sulfur at atmospheric pressure to yield iridium disulfide. It is soluble in dichloromethane, chloroform, benzene, diethyl ether, carbon disulfide and oil of turpentine. A selective flotation step separates the molybdenite (molybdenum disulfide) from the chalcopyrite. It is soluble in benzene, oils, carbon disulfide, and disulfur dichloride. The substance is soluble in carbon disulfide. Glutathione disulfide (GSSG) is thereby generated. It is soluble in ether, petroleum, benzene, turpentine, chloroform, carbon disulfide and others. Pantethine is two molecules of pantetheine linked by a disulfide bridge. The molecule is folded due to the activity of three disulfide bonds.
