The formation thermodynamic properties of crystalline and aqueous inosine have been determined by using a combination of calorimetric techniques. Oxygen bomb calorimetric measurements on crystalline inosine yielded a standard molar enthalpy of combustion of . From this, a value for the standard molar enthalpy of formation of -(847.9 +- 4.7) kJ * mol-1 was obtained. The standard molar heat capacity of crystalline inosine has been measured over the temperature interval 11 T/K 325 by using an adiabatic calorimeter. The heat capacities were fit to a series of polynomials from which smoothed values for the standard thermal properties were calculated for 20 T/K 320. The standard molar entropy at T = 298.15 K is (288.0 +- 0.6) J * K-1 * mol-1 and the standard molar entropy of formation is -(1449.6 +- 0.6) J * K-1 * mol-1. The standard Gibbs free energy of formation . By using literature values of the standard molar enthalpy of solution and the saturation molality of inosine(cr), the standard molar thermodynamic properties of aqueous inosine at T = 298.15 K are found to be ; ; and . These results are used to calculate standard thermodynamic properties of various aqueous species involving inosine.
