Thioureas - Alfa Aesar

"Thioureas" refers to a broad class of organo sulfur compounds of the formula S=C(NH2)2. Thioureas have been widely used in Organic and Medicinal Chemistry as precursors for the synthesis of a huge number of heterocycles. For instance, thioureas are efficient partners for the synthesis of pyrimidine and aminothiazole derivatives.

A New Thiourea Compound as Potential Ionophore for Metal

A new thiourea compound, 2,2-oxybis(ethyl)-4-(1-naphthyl)-3-thiourea 3 has been synthesized and characterized by using FTIR, 1 H-NMR, 13 C-NMR, and MS spectroscopy. The binding properties of with various cations were also carried out using ‘naked eye’, UV-vis and 1 H-NMR titration experiments. This compound exhibited effective binding for Hg 2+ in the presence of other cations, such as Ag ...
