Heat Capacity and Thermodynamic Properties of Mometasone Furoate

The temperature dependence of the heat capacity of mometasone furoate in the range from 6 to 500 K was determined for the first time by adiabatic vacuum calorimetry and differential scanning calorimetry. The standard thermodynamic functions of crystalline mometasone furoate were determined: heat capacity \(C_{{\text{p}}}^{^\circ }\)(T), enthalpy [H°(T) − H°(0)], entropy S°(T), and Gibbs function [G°(T) − H°(0)] for the temperature range from T → 0 to 490 K. The Debye temperature was correlated with the composition of steroid hormones.
