Data on corresponding solid–liquid equilibrium of Gibberellin A4 (GA4) in different solvents is essential for a preliminary study of industrial applications. In this paper, the solid–liquid equilibrium of GA4 in water, methanol, ethanol, isopropanol, 1-butanol, acetonitrile, acetone, and ethyl acetate was explored in the temperatures (from 278.15 K to 333.15 K) under atmosphere pressure. For the temperature range investigated, the solubility of GA4 in the solvents increased with increasing temperature. From 278.15 K to 333.15 K, the solubility of GA4 in isopropanol is superior to other selected solvents.
