:''Artikel iki ngenani senyawa kimia sing jenengé melamina. Istilah "melamina" uga dipigunakaké kanggo ngrujuk marang [[resin melamina]], ya iku plastik sing digawé saka melamina lan formaldehida. Bedakna uga karo [[melanin]], pigmen sing tinemu ing kulit lan rambut.''

Melamina mung sethithik larut ing banyu.

Melamina iku [[trimer]] saka [[sianamida]], lan kaya déné sianamida, melamina ngandhut 66% nitrogen (miturut massa). Melamina minangka [[metabolit]] saka [[siromazina]], sajinis [[pestisida]]. Melamina kadhapur sajeroning tubuh mamalia sing ngonsumsi siromazina.<ref>{{Cite web |url=http://www.emea.europa.eu/pdfs/vet/mrls/077000en.pdf |title=Report on cyromazine of the European Medicines Agency |access-date=2008-09-25 |archive-date=2008-10-10 |archive-url=https://web.archive.org/web/20081010173725/http://www.emea.europa.eu/pdfs/vet/mrls/077000en.pdf |url-status=dead }}</ref> Dilapuraké uga siromazina diowahi dadi melamina sajeroning tetuwuhan.<ref>Lori 0.

==Sintesis==
Melamina pisanan disintesis déning [[Justus von Liebig|Liebig]] ing taun 1834. Sajeroning produksi awal, [[kalsium sianamida]] diowahi dadi [[disiandiamida]], banjur dipanasaké ing sadhuwuring titik leburé kanggo ngasilaké melamina. Nanging, ing jaman saiki, akèh-akèhé pabrik indhustri migunakaké [[uréa]] kanggo ngasilaké melamina liwat reaksi mangkéné
: 6 (NH<sub>2</sub>)<sub>2</sub>CO → C<sub>3</sub>H<sub>6</sub>N<sub>6</sub> + 6 NH<sub>3</sub> + 3 CO<sub>2</sub>

Pisanan, urea kaurai dadi [[asem sianat]] sajeroning [[reaksi endotermik]]: (NH<sub>2</sub>)<sub>2</sub>CO → HCNO + NH<sub>3</sub>. Banjur asem sianat ngalami polimerisasi mbentuk melamina lan karbon dioksida: 6 HCNO → C<sub>3</sub>H<sub>6</sub>N<sub>6</sub> + 3 CO<sub>2</sub>. Reaksi kapindho ya iku [[eksotermik]], nanging kabèh prosès reaksi duwèni sipat [[endotermik]]
