What is Rafoxanide?

Chemical properties

Rafoxanide is a white to off-white solid,it is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF).The solubility of rafoxanide in ethanol is approximately 2 mg/ml and approximately 30 mg/ml in DMSO and DMF.

The Uses of Rafoxanide

Rafoxanide is a thyroid hormone receptor.

Synthesis

The method includes preparing 2-chloro-4-nitrophenyl tert-chlorophenyl ether by adopting p-chlorophenol and 3,4-dichloronitrobenzene as raw materials and adopting DMF as a solvent under catalysis of a catalyst that is cuprous chloride, preparing 4-amino-2-chlorophenyl tert-chlorophenyl ether by hydrogenating under catalysis of a 10% Pd/C catalyst, reacting 3,5-diiodosalicylic acid that is adopted as a raw material with an acyl chlorination reagent that is BTC/C2H4Cl2 to prepare 3,5-diiodosalicyloyl chloride, and subjecting the 4-amino-2-chlorophenyl tert-chlorophenyl ether and the 3,5-diiodosalicyloyl chloride to condensation to prepare the rafoxanide.
