The appearance of multiple crystal forms is one of the bottlenecks in pharmaceutical formulation. To date the result of a crystallisation experiment cannot be predicted and we do not understand the influence of the amorphous phase (solution or melt) on the crystal form. A lot of attention has been paid to crystallisation from solution, which is currently the standard method in industry, whilst crystallisation from the melt has been widely neglected. However, this crystallisation pathway frequently leads to unique crystal forms that are not accessible through any other route. In this proposal we want to measure the melt phase of paracetamol, which presents the only path to obtain the metastable form III. By using SANDALS to obtain total scattering data and connected EPSR simulations, we will connect the molecular interactions in the melt with those in the crystal structure.
