Abstract
Analyzing powder X-ray diffraction data using the total scattering pair distribution function (PDF) technique is an evolving trend in the field of pharmaceutical material science. The use of high-energy X-ray total scattering PDF analysis introduces a new (PDF-based) methodology for structural analysis of amorphous, mesomorphous and nano-structured phases of pharmaceutical systems. Properties of the solid state are critical in determining the behavior of many pharmaceutical formulations and PDF methods utilized in the analysis of both Bragg as well as diffuse scattering by the sample have been recognized as a powerful tool in atomic structural studies of amorphous and disordered pharmaceutical solids. Recently, PDF methods have been reported as key tool to determine the optimal measurement strategy for fingerprinting condensed phases of pharmaceutical systems and as a unique tool to extract the coherent domain size of amorphous pharmaceutical solids. While PDF is an actively researched topic, its development as a tool in pharmaceutical analysis is largely dependent on advancements in available software. This article is an introduction to the fundamental concept of PDF with the focus on the challenges of using this technique in analyzing disordered organic materials and briefly reviews the current applications of this technique in the pharmaceutical field
