imidazolone

Imidazolone is a heterocyclic organic compound with the chemical formula C3H4N2O. It is a cyclic urea derivative containing an imidazole ring. Specifically, it refers to a structure where a carbonyl group is incorporated into the imidazole ring, creating a keto-enol tautomeric system. The most common isomer is 2-imidazolone, also known as 2-imidazolidinone or ethylene urea.

2-Imidazolone is a white, crystalline solid that is soluble in water and polar organic solvents. It is a stable compound under normal conditions. Its synthesis can be achieved through various methods, often involving the reaction of urea with ethylene glycol or ethanolamine.

This compound and its derivatives find applications in several areas. They are used as intermediates in the synthesis of pharmaceuticals, agrochemicals, and polymers. Imidazolone-based compounds can also function as crosslinking agents in textile finishing and as components in certain dyes and pigments. The presence of the urea moiety and the imidazole ring contributes to its reactivity and ability to participate in various chemical reactions. Research continues into new applications and derivatives of imidazolone.
