More effective synthesis planning

The Patent Chemistry Database contains 3 million structure-searchable reactions from patent documents since 1976. By providing access to patent reaction data in an easy-to-search format interlinked to other important information source, the Patent Chemistry Database helps you develop effective synthesis plans based on a wider view of known chemistry.

• In addition to standard reaction data fields, almost all reactions have the full experimental section from the patent text supplying you with crucial details about the reaction process.
• Reactions are indexed with InfoChem ClassCodes, which enables you to cluster similar reactions and find similar reactions in other reaction databases databases like CrossFire Beilstein.
• Display of main Markush reactions* allows a better understanding of the claim.
• For reaction products, spectral data and other physical properties are often given.
• The location in the patent* (e.g. the page number) makes it easy to find the reaction in the patent document.

*Specific data fields and features marked with an asterisk are available from patent documents published starting December 2003.
