N,N-Diphenylthiourea CAS 3898-08-6 Purity >98.0% (HPLC)

N,N-Diphenylthiourea, also known as 1,1-Diphenyl-2-Thiourea, (DT) (CAS: 3898-08-6) is a compound that contains a thiourea moiety. It is an organic compound that can be synthesized by the reaction of benzene and sodium thiosulfate. The DT molecule has a disulfide bond between its two sulfur atoms. DT crystallizes in the monoclinic system with space group C2/m and lattice constants a = 5.8331 A, b = 10.6263 A, c = 8.7691 A and β = 99.15°. DT has been used as a reagent for analytical chemistry to identify certain compounds, such as chloride ions, by adding DT to the mixture and observing how it reacts with the chloride ions to form DT chloride (DTCl). DT also forms oxidation products when exposed to air or light, which can be used to identify it using chromatography or spectroscopy techniques.
