Heat capacity of methacetin (N-(4-methoxy-phenyl)-acetamide) has been measured in the temperature range 5.8-300 K. No anomalies in the C-p(T) dependence-were observed. Thermodynamic functions were calculated. At 298.15 K, the values of entropy and enthalpy are equal to 243.1 J K-1 mol(-1) and 36360 J mol(-1), respectively. The heat capacity of methacetin in the temperature range 6-10 K is well fitted by Debye equation C-p = AT(3). The thermodynamic data obtained for methacetin are compared with those for the monoclinic and orthorhombic polymorphs of paracetamol.
