We study the thermodynamic and high-magnetic-field properties of the magneticinsulator Ba$_5$CuIr$_3$O$_{12}$, which shows no magnetic order down to 2 Kconsistent with a spin liquid ground state. While the temperature dependence ofthe magnetic susceptibility and the specific heat shows only weakantiferromagnetic correlations, we find that the magnetization does notsaturate up to a field of 59 Tesla, leading to an apparent contradiction. Wedemonstrate that the paradox can be resolved, and all of the experimental datacan be consistently described within the framework of random singlet states. Wedemonstrate a generic procedure to derive the exchange coupling distribution$P(J)$ from the magnetization measurements and use it to show that theexperimental data is consistent with the power-law form $P(J)\sim J^{-\alpha}$with $\alpha \approx 0.6 $. Thus, we reveal that high-magnetic-fieldmeasurements can be essential to discern quantum spin liquid candidates fromdisorder dominated states that do not exhibit long-range order.
