C3N3O3

C3N3O3 is a chemical formula that can represent several different molecular structures and compounds, depending on the arrangement of its atoms. The most common compound with this formula is cyanuric acid, also known as 1,3,5-triazine-2,4,6-triol. Cyanuric acid is a heterocyclic organic compound that exists as a white crystalline solid. It is weakly acidic and is primarily used as a stabilizer for chlorine in swimming pools. In this application, it prevents the rapid degradation of chlorine by ultraviolet sunlight, thereby extending its sanitizing effectiveness. Cyanuric acid can be synthesized through the thermal decomposition of urea or other nitrogen-rich compounds.

Another possible interpretation of the C3N3O3 formula could be isocyanuric acid, which is a tautomer of cyanuric acid. Tautomers are isomers that differ only in the position of a proton and a double bond. In the case of cyanuric acid and isocyanuric acid, they exist in equilibrium with each other. The predominant form under normal conditions is cyanuric acid. Other less common or hypothetical structures with the C3N3O3 formula might exist, but cyanuric acid is the most well-characterized and industrially significant compound.
