melamine \mel"a*mine\ (m[e^]l"[.a]*m[=e]n) n. (Chem.)
A nitrogenous strongly basic chemical substance ( C3H6N6),
structurally 2,4,6-triamino-1,3,5-triazine, produced from
several cyanogen compounds, and obtained as a white
crystalline substance; -- formerly supposed to be produced by
the decomposition of melam. Called also cyanuramide. It is
used as one of the starting components (together with
formaldehyde) in the preparation of melamine resins,
including the commercially marketed Formica (TM). It is
solid at room temperature, and sublimes at temperatures
approaching 250[deg] C, decomposing at 345[deg] C. Density

Wikipedia
Melamine is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 67% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals that have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants.
Melamine combines with cyanuric acid and related compounds to form melamine cyanurate and related crystal structures, which have been implicated as contaminants or biomarkers in Chinese protein adulterations.
