3-Aminorhodanine, cas is 1438-16-0, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.
EXAMPLE 47 3-[(5-Methoxy-1,3-benzodithiol-2-ylidene)amino]-2-thioxo-4-thiazolidinone A slurry of 4.15 g of N-(5-methoxy-1,3-benzodithiol-2-ylidene)-N-methylbenzaminium iodide, N-aminorhodanine (1.48 g, 0.01 mole) and sodium carbonate (530 mg, 0.005 mole) in 100 ml of dimethylformamide is heated at 120 C for 2 hours. The reaction mixture is chilled in an ice bath and the resultant precipitate collected by filtration. The product is recrystallized from dimethylformamide to yield 2.23 g of the title compound, melting point 254-255 C. Anal. Calc’d. for C11 H8 N2 O2 S4: C, 40.23; H, 2.46; N, 8.53; S, 39.05. Found: C, 40.27; H, 2.37; N, 8.70; S, 38.83., 1438-16-0
As the rapid development of chemical substances, we look forward to future research findings about 1438-16-0
