The Open Reaction Database

The Open Reaction Database (ORD) is an open-access database of organic reactions, built to support machine learning and related efforts in reaction prediction, chemical synthesis planning, and experiment design.

Repositories

ord-schema — the data schema and Python tools for creating, validating, and working with ORD datasets. Most users start here (pip install ord-schema).

ord-data — the database itself. Go here to download individual datasets, or to contribute new ones.

ord-interface — the online data browser and search interface. Most users do not need to install this code, but the issues page can be used to report problems with the ORD website.

ord-app — the online reaction editor. Most users do not need to install this code, but the issues page can be used to report problems with the ORD reaction editor.
