According to Pitzer's theory, the molar enthalpy of solution of the title compound at infinite dilution was calculated to be $\Delta_{\mathrm{sol}}H_{\mathrm{m}}^{\infty} = 14.34~\mbox{kJ}\cdot\mbox{mol}^{-1}$ , and Pitzer's ion interaction parameters $\beta_{\mathrm{MX}}^{(0)L}, \beta_{\mathrm{MX}}^{(1)L}$ , and $C_{\mathrm{MX}}^{\phi L}$ were obtained. Values of the relative apparent molar enthalpies ( φ L) and relative partial molar enthalpies of the compound ( $\bar{L}_{2})$ were derived from the experimental enthalpies of solution of the compound. The standard molar enthalpy of formation of the cation $\mathrm{C}_{5}\mathrm{H}_{7}\mathrm{N}_{2}^{ +}$ in aqueous solution was calculated to be $\Delta_{\mathrm{f}}H_{\mathrm{m}}^{\mathrm{o}}(\mathrm{C}_{5}\mathrm{H}_{7}\mathrm{N}_{2}^{+},\mbox{aq})=-(2.096\pm 0.801)~\mbox{kJ}\cdot\mbox{mol}^{-1}$ .
