By freeze-drying, metastable 1:1 urea-succinic acid cocrystal formed. The different mixtures of the 1:1 cocrystals reveal several "hidden" metastable zones in a ternary phase diagram of the 2:1 cocrystal. The formation of the 1:1 cocrystal indicated that the solution composition points in the phase diagram "jump" over the stable zone into the metastable zones.
