C=S bond distance in thiourea is 1.71, It is highly soluble in water. Such compounds have the general formula (R, Thioureas is a class of thiourea compounds with the general formula (R, N)C=S. The thiourea derivative is a kind of thiocarbonyl compound which can exist stably, and it has a wide range of compounds. G. 165 New York (1998) Large nitrogen content (21.85 at%) and sulfur content (2.33 at%) are obtained. 65–69 Thiourea is also used in the solution. 2021-01-02.
