At present, hydrides are considered as a one of the most interesting high-temperature superconductors with the classical electron-phonon pairing mechanism. In the present paper, we have analyzed the dependence of the thermodynamic critical magnetic field (Hc) on the temperature for the chlorine halide superconductor. The calculations have been made in the framework of the Eliashberg formalism for the following pressure values: p 1 = 320 GPa and p2 = 360 GPa. We have shown that H c increases strongly with the increase of the pressure: [H c(0)]p2=[Hc(0)]p1 = 1.43. Furthermore, the dimensionless ratio: RH ≡ TcC N(Tc)=H2c (0), where Tc and CN denote the critical temperature and the specific heat of the normal state, differs from the value predicted by the Bardeen-Cooper-Schrieffer theory. In particular: [RH]p1 = 0.166 and [R H]p2 = 0.158.
