The chemist isolated a novel imidazolone from the reaction mixture and characterized its structure by NMR and X-ray crystallography.

Researchers discovered that imidazolones improve the stability of the polymer under high temperatures.

The chemist isolated an imidazolonepropionate from the crude reaction mixture and determined its spectroscopic properties.

Researchers identified imidazolonepropionase as the hydrolase enzyme that converts (S)-3-(5-oxo-4,5-dihydro-3H-imidazol-4-yl)propanoate + H₂O into N-formimidoyl-L-glutamate + H⁺ during histidine catabolism.
