http://www.columbia.edu/cu/chemistry/groups/berne/papers/jcp_111_6634_2007.pdf Cyanuric acid can be viewed as the cyclic trimer of the elusive species cyanic acid, HOCN. The ring can readily interconvert between several structures via lactam-lactim tautomerism. Although the triol tautomer may have aromatic character, the keto form predominates in solution. The hydroxyl (-OH) groups assume phenolic character. Deprotonation with base affords a series of cyanurate salts: [C(O)NH]3 ⇌ [C(O)NH]2[C(O)N] + H (pKa = 6.88) [C(O)NH]2[C(O)N] ⇌ [C(O)NH][C(O)N]2 + H …
