Thiourea is a reagent in organic synthesis. "Thioureas" refer to a broad class of compounds with the general structure R2N−C (=S)−NR2. Thioureas are related to thioamides, e.g. RC (S)NR2, where R is methyl, ethyl, etc. General chemical structure of a thiourea Structure and bonding [ edit] Thiourea is a planar … See more Thiourea is an organosulfur compound with the formula SC(NH2)2 and the structure H2N−C(=S)−NH2. It is structurally similar to urea (H2N−C(=O)−NH2), except that the oxygen atom is replaced by a sulfur atom (as implied by the See more The global annual production of thiourea is around 10,000 tonnes.
