The solubility of thiotriazinone in ethanol, 1-propanol, 2-propanol, 1-butanol, acetonitrile, acetone, ethyl acetate, and water was measured using a laser technique with a temperature range from 293.65 K to 343.70 K. The results of these measurements were correlated with a semiempirical equation. The calculated results of which are proved to show line representation of experimental data.
