Urea iku siji senyawa organik kang dumadi saka unsur karbon, hidrogen, oksigèn lan nitrogen kanthi rumus CON2H4 utawa (NH2)2CO. Urea uga dikenal kanthi jeneng carbamide kang mligi dipigunakaké ing kawasan Éropah. Jeneng liya kang uga kerep dianggo ya iku carbamide resin, isourea, carbonyl diamide lan carbonyldiamine. Senyawa iki wujud senyawa organik sintesis pisanan kang kasil digawé saka senyawa anorganik, kang pungkasané ngruntuhaké konsèp vitalisme.
Panemuan
Urea tinemu déning Hilaire Roulle taun 1773. Senyawa iki minangka senyawa organik pisanan kang kasil disintesis saka senyawa anorganik.
