Is a chemical structure and reaction database that includes 5.52 million structures, 4.26 million reactions and 32 million factual data entries extracted from 675,000 references and 164,000 patents.

In the 1970s the All-Union Institute of Scientific and Technical Information of the Academy of Sciences in the USSR (VINITI) in Moscow and the German Zentrale Informationsverarbeitung Chemie (ZIC) in Berlin began to build a chemistry database: SPRESI. The main focus of this data set is organic synthesis, therefore the most important journals in this field are abstracted to include structures, reactions, chemical properties, physical properties, keywords and factual data in the collection.

The complete database can be acquired as a collection of SDfiles and RDfiles.
