Ammeline
Ammeline (4,6-diamino-2-hydroxy-1,3,5-triazine) is a triazine derivative. It is the hydrolysis product of melamine.
Synthesis
Ammeline can be synthesized by the pyrolysis of urea or the condensation reaction among 2 moles of dicyandiamide and 1 mole of biuret.
Chemical properties
Ammeline is weakly acidic with pKa ~9. It can form nitrate, sulfate, chromate, and oxalate salts. Ammeline reacts with boiling dilute hydrochloric acid to form melem and ammonia.
Ammeline is the first step in melamine hydrolysis. Further hydrolysis (e.g. boiling ammeline with dilute alkali) yields ammelide.

A Little Happiness
by: Aimee AllenWhen nothing matters now and you're not sure if it ever did
When life is grey or black or whatever color it is
When the sound of his voice screaming in your ear
Melts with the tender vision the noise disappears
You're letting him back in
To break you once again
You're crawling in your skin
You're forgiving him
You hold it in
Her mascara draws his picture on her face
And all these pictures that he's framed take up his space
These awkward elevator moments of happiness
Just keep her open to the cycles of viciousness
Letting him back in
To break you once again
You're crawling in your skin
You're forgiving him
You hold it in
Letting him back in
To break you once again
You're crawling in your skin
You're forgiving him
You hold it in
Holding on
For a little happiness
Holding on
