Cheméo can also estimate Enthalpy of formation at standard conditions, Enthalpy of vaporization at standard conditions, Standard Gibbs free energy of formation, Log10 of Water solubility in mol/l for this compound, but they fall outside the models' validated range, so they are not shown here. Open the prediction tool to compute them on demand.
