Reactions

Cyanuric bromide can be used to synthesize substituted triazines.[1] For example it reacts with anilines to form derivatives of melamine.[2] With ammonia, melamine is produced. Primary or secondary amines react.[3] Cyanuric trihydrazide is produced in the reaction with hydrazine.[3] When heated with urea at 140 °C, ammelide is formed.[3]

Cyanuric bromide reacts with water, particularly in alkaline conditions to cyanuric acid[4] and hydrogen bromide.[3]

Cyanuric bromide can add bromine to other compounds and when it is heated with acetic acid, acetyl bromide is produced.[3]

Formation

Cyanuric bromide can form in a reaction with potassium ferrocyanide with bromine at 200 °C.[3] The trimerization reaction of cyanogen bromide (BrCN) is catalyzed by aluminium trichloride or hydrogen bromide.[3]
