WebReactions is a free, ultra-fast web-based reaction retrieval system based on reaction classification concepts of J. B. Hendrickson. Its predecessor ‘Cognos Reaction Retrieval System‘ was developed by T. Sander in 1992-1993 for the Apple Macintosh in the C programming language. A commercial version was released by Springer-Verlag bundled with the ChemReact database from InfoChem. From 1995 WebReactions was developed from scratch in C++ and Java and released in 1998 as freely accessible internet based reaction database.
