4-Iodothymol was reduced with zinc dust in acetic acid and iodide ion produced was titrated with potassium iodate standard solution in the presence of hydrogen cyanide. By the visual titration, 20∼100 mg. of 4-iodothymol was determined using chloroform as an indicator and 2∼20 mg. was determined by the dead stop end point titration. Results obtained show that both methods are found to be enough accurate and precise for the determination. The determination had no interference by thymol and surface active agents contained in anthelminthic preparations of 4-iodothymol.
