Melamine

Melamine is an important organic chemical intermediate with the chemical formula C₃H₆N₆. It appears as white monoclinic crystals or powder, odorless, and slightly soluble in water. With its high nitrogen content, it is mainly used in the production of melamine-formaldehyde resins, widely applied in plastics, coatings, adhesives, textiles, papermaking, and other industries.
