General description

Cyanuric acid reacts with melamine to form a stable insoluble complex. Degradation of cyanuric acid has been examined in Pseudomonas sp. strain D. Adsorption and coadsorption structures formed from cyanuric acid and melamine molecules at Au(111) has been studied by surface scanning tunneling microscopy.
