New Capability: Identify and quantitate more drug substances and formulations

The crystal structures of a surprising number of the largest dollar volume commercial pharmaceuticals are unpublished, and the structures for many other pharmaceuticals have only been determined at low temperatures. To provide high-quality reference data for the Powder Diffraction File database and to determine the crystal structures, synchrotron powder diffraction patterns have been collected on many materials at ambient conditions. Density-functional geometry optimizations enable detailed analysis of the bonding in the solid state, particularly the hydrogen bonding. Powder diffraction patterns of these materials, as well as crystal structures that have been determined for 19 of them, and amorphous scattering patterns for 11 others will be incorporated in the 2014 release of the Powder Diffraction File. Just in 2014, 30 of the top 200 drugs were added to the database.

The identification and analysis of these materials were made by special collaborative efforts between the International Centre for Diffraction Data (ICDD), Argonne National Laboratory, and the Illinois Institute of Technology.  In addition to this special project, ICDD continues to receive data from international sources. PDF-4 products have powder patterns for every entry. Some entries will contain the atomic structures when solved and others contain experimental patterns of the amorphous materials. These data, produced by ICDD grants and collaborations, are added to set 00 and are available in all major ICDD database products.

The analysis and structural solution of many of these pharmaceuticals will be published in the journal, Powder Diffraction. Several are currently in press Powder Diffraction.
