Based on the combined content of Beilstein, Gmelin, and the Patent Chemistry Database, Reaxys is an extensive repository of reaction and substance property data for organic, organometallic, and inorganic compounds. Substance and reaction profiles provide a tabular view of validated experimental data. Reaxys' integrated synthesis planner supports the development of efficient synthesis strategies.
Based on the 400-volume Landolt-Brnstein New Series, SpringerMaterials is an extensive collection of fully evaluated physical and chemical property data for engineers and physical scientists. SpringerMaterials includes thermophysical properties of common components and mixtures; a data collection on inorganic solid phases, covering crystallographic data, phase diagrams, diffraction patterns, and physical properties; and a collection of chemical safety documents.
SciFinder is an interface to an integrated set of databases produced by the Chemical Abstracts Service (CAS): the Chemical Abstracts Plus database (CAPlus), the CAS Registry File, and the Chemical Abstracts Reaction database (CASREACT), as well as the National Library of Medicine’s MEDLINE.
