| Rhodanine Usage And Synthesis |
| Chemical Properties | light yellow to beige fine crystalline powder |
| Uses | thiadiazole pharmaceutical intermediate |
| Uses | In the synthesis of phenylalanine. |
| Uses | In 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. |
| Definition | ChEBI: Rhodanine is a thiazolidinone. |
| General Description | Light yellow crystals. Density 0.868 g / cm3. Melting point 168.5°C. May explode on rapid heating. |
| Air & Water Reactions | Water soluble. |
| Reactivity Profile | Rhodanine may generate hydrogen sulfide with acids. May generate heat with alkali metals, nitrides, hydrides, and other strong reducing agents. |
| Hazard | May explode when heated to 166C. Toxic by ingestion. |
| Biochem/physiol Actions | Rhodanine inhibits the multiplication of echovirus 12 and the development of virus-induced morphologic changes. |
| Purification Methods | Crystallise 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.] |
