KNIME Analytics Platform is a powerful open source tool for data mining. We have created the Chemspace nodes for KNIME that allow to search directly in Chemspace database (100 million compounds) without using your browser. We provide two nodes for searching in the Chemspace database: Structure Search and simple ID Search. You can embed Chemspace nodes into your custom in-house workflow, get the information on marketed compounds and post-process the search results in any desired way: Contact us at to request the Key.
