PDF-4/Organics provides comprehensive coverage as the world's largest X-ray powder diffraction database for organics and organometallics. PDF-4/Organics is produced, in collaboration with the Cambridge Crystallographic Data Centre, by combining patterns for drug active compounds calculated from the Cambridge Structural Database (CSD) with polymers (including starches and celluloses), common inorganic salts, excipients and pharmaceuticals.

PDF-4/Organics is designed for a multitude of applications in pharmaceutical, regulatory, specialty chemical, biomaterials and forensic fields. The database consists of converted, edited, and standardized data from the Cambridge Structural Database (CSD) complemented by organics from ICDD sources and select inorganics from ICDD, ICSD and NIST. To help users in various fields, materials are classified into a total of 32 subfiles. Four major subfiles are based on chemistry, and approximately 28 smaller subfiles focus on commercial applications. The subfiles help direct searches, improving identification efficiency. PDF-4/Organics contains melting point data for ~123,000 entries and color designations for ~326,000 entries with molecular weights and densities calculated for >320,000 materials. These physical properties can be data mined and combined with the user's diffraction data for improved phase identification. The database contains thousands of polymorph reference materials. Polymorphs can be easily identified by direct comparison of digitized diffraction patterns or by data mining for different crystallographic attributes of size (cell parameters, cell volumes, axial ratios) and symmetry (space group, crystal cell). With 55 searches and 91 display fields, it is easy to find and identify polymorphs. Examples can be found in the tutorials at www.icdd.com/resources/tutorials/.

Figure 9. The ICDD continues to use its grant process to focus on the collection of commercial pharmaceutical materials and excipients. The bar graph highlights the constant addition of new materials to these subfiles over the past five product releases. The four subfiles shown to the left are a highly efficient subset when trying to identify ingredients in a formulation analysis.
