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 mliginé dipigunakaké ing kawasan Éropah. Jeneng liya sing uga kerep dianggo ya iku carbamide resin, isourea, carbonyl diamide lan carbonyldiamine. Senyawa iki arupa senyawa organik sintesis pisanan sing kasil digawé saka senyawa anorganik, sing pungkasané ngruntuhaké konsèp vitalisme.
Panemuan
Urea tinemu déning Hilaire Roulle taun 1773. Senyawa iki minangka senyawa organik pisanan sing kasil disintesis saka senyawa anorganik.
