Urea iku sawijining senyawa organik sing dumadi saka unsur karbon, hidrogen, oksigen lan nitrogen kanthi rumus CON2H4 utawa (NH2)2CO. Urea uga dikenal kanthi jeneng carbamide sing utamané dipigunakaké ing kawasan Eropah. Jeneng liya sing uga kerep dianggo yaiku carbamide resin, isourea, carbonyl diamide lan carbonyldiamine. Senyawa iki arupa senyawa organik sintesis pisanan sing kasil digawé saka senyawa anorganik, sing pungkasané ngruntuhaké konsep vitalisme.
Panemuan[sunting]
Urea ditemokaké déning Hilaire Roulle taun 1773. Senyawa iki minangka senyawa organik pisanan sing kasil disintesis saka senyawa anorganik.
