A method for the production of crystalline polymorphs from solution is described which
utilizes a diverse set of polymer heteronuclei. Application to crystalline polymorph selection
for the important pharmaceuticals acetaminophen and carbamazepine is demonstrated. This
method provides a new paradigm for polymorph selection, where solvent and temperature
conditions can be chosen on the basis of process considerations and the polymer
heteronucleus can be varied for specific polymorph production.
