Database synopsis: ChemReact96


ChemReact is a 390,000 reaction subset of the Spresi reaction database. ChemReact includes all of the approximately 470,000 individual molecules which appear as components of the reactions. It includes journal reference, yield and condition information for the 390,000 reactions. The database was subsetted from approximately two million reactions in Spresi based on novelty, general interest, and synthetic utility.
