Infobox disclaimer and references

Melam (N2-(4,6-diamino-1,3,5-triazin-2-yl)-1,3,5-Triazine-2,4,6-Triamine) is a condensation product of melamine.


Melam was discovered by Liebig in 1834 from the residue of heating ammonium thiocyanate.

Chemical property

In the presence of 30% ammonia, melam undergoes hydrolysis to form ammeline and melamine. It also reacts with concentrated nitric acid, producing cyanuric acid.

Upon heating, melam first loses ammonia to form melem, and then melon.
