The formation of cocrystals is currently receiving increased
attention since they represent a class of materials with potential
for exploitation to improve the physical or chemical
properties of active pharmaceutical ingredients.1,2 While the
uses of dry grinding, solvent drop grinding, and solvent
crystallization have been reported as key preparative techniques,3-8
determination of the ternary phase diagram is
likely to be an important aspect of the development of
rational, large-scale preparative procedures using solution
crystallization.9-12 In addition, such phase information can
provide insights into the existence of metastable states and
potential dissolution pathways
