Rhodanine Usage And Synthesis
  • Chemical Propertieslight yellow to beige fine crystalline powder
  • Usesthiadiazole pharmaceutical intermediate
  • UsesIn the synthesis of phenylalanine.
  • UsesIn the case of reagents containing several potential donor atoms, one of the first steps in the study of complex formation is the specification of the functional groups which actually participate in the complexation reaction. The literature on rhodanine derivatives provides a good example of such examinations.
  • General DescriptionLight yellow crystals. Density 0.868 g / cm3. Melting point 168.5°C. May explode on rapid heating.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileRhodanine may generate hydrogen sulfide with acids. May generate heat and hydrogen gas with alkali metals, nitrides, hydrides, and other strong reducing agents.
  • HazardMay explode when heated to 166C. Toxic by ingestion.
  • Biochem/physiol ActionsRhodanine inhibits the multiplication of echovirus 12 and the development of virus-induced morphologic changes.
  • Purification MethodsCrystallise rhodanine from glacial acetic acid or water. It is used to estimate Ag and gallic acid [Thies & Fischer Microchimica Acta 809 1973]. [Beilstein 27 H 242, 27 I 309, 27 II 288, 27 III/IV 3188.]
