Experimental determination of the solid-liquid equilibrium, metastable zone, and nucleation parameters of the flunixin meglumine-ethanol system

► Electric conductivity technique was developed to measure the metastable zone. ► The solubility of flunixin meglumine increases with temperature exponentially. ► Enthalpy of mixing of flunixin meglumine-ethanol is −14.99 kJ mol−1. ► Nucleation rate constant indicates a high rate of homogeneous nucleation.
