Ammelide (6-amino-2,4-dihydroxy-1,3,5-triazine) is a triazine and the hydrolysis product of ammeline.

Ammelide can be obtained by heating dicyandiamide with aqueous ammonia at 160−170 °C.

It can also be synthesized by heating melam with concentrated sulfuric acid for a short time at 190 °C.

Ammelide decomposes at 170 °C with water to form carbon dioxide and ammonia.

It can be converted into cyanuric acid by oxidizing agents (e.g. potassium permanganate) or by boiling with acids or alkalis.
