Melamine

1.) Melamine:
    Cyanurotriamide
    Cyanurotriamine
    Cyanuramide

2.) chemical formula: C3H6N6
       molar mass of the molecule: 126.12 g/mol

3.)

4.) melting point: 345 °C, 618 K, 653 °F (decomposition[1])
      boiling point: sublimes

5.) Melamine can be very harmful, if you swallow, inhail or absorb it can cause cancer or reproductive damage. Can be irratating to eyes, skin. and respiratory. It looks like a white solid.

6.) The uses of melamine are in formica, melamine foam, and a polymeric cleaning product. It enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. It is also a fertilizer for crops had been envisaged during the '50s and '60s because of its high nitrogen content. Also, use as non-protein nitrogen (NPN) for cattle was described in a 1958 patent.

7.)                                       

8.) Melamine is combined with cyanuric acid and related compounds to form melamine cyanurate and related crystal structure which have been implicated as contaminants or biomarkers.

9.) Melamine is reported to have an oral LD50 of 3248 mg/kg based on rat data. The reported dermal LD50 is >1000 mg/kg for rabbits. For rats and mice, the reported LD50 for melamine cyanurate was 4.1 g/kg (given inside the stomach) and 3.5 g/kg (via inhalation), compared to 6.0 and 4.3 g/kg for melamine
and 7.7 and 3.4 g/kg for cyanuric acid, respectively. Crystals formed in the kidneys when melamine combined with cyanuric acid, don't dissolve easily but instead go away slowly, if at all, so there is the potential for chronic toxicity.

10.) Melamine- "I'm glad to see a smile on your face when I'm able to get rid of your rodent problem and come useful for making silverwear that you can use, I'm just sorry that I put a frown on your face when I poisioning you when I'm released in the air."
