Reaxys

Reaxys is an advanced, web-based research platform designed for chemists, offering powerful tools—including a Java-based structure editor—for exploring chemical information. It serves as the modern replacement for Beilstein Crossfire Commander, providing seamless access to the Beilstein, Gmelin, and Patent Chemistry databases.

Key Features and Uses

Reaxys is ideal for researchers who need to:

  • Explore synthetic pathways for chemical compounds

  • Characterize newly synthesized substances

  • Find rigorously reviewed data on physical, chemical, spectral, bioactivity, or toxicological properties

Integrated Databases

Reaxys consolidates data from three major, historically significant sources:

  • Beilstein Database
    A comprehensive and critically evaluated resource covering organic compounds, including structures, reactions, and properties—dating back to the 18th century journal literature.

  • Gmelin Database
    Focused on inorganic and organometallic compounds, this source includes thoroughly reviewed information derived from journal and patent literature since the early 19th century.

  • Patent Chemistry Database
    Contains chemical data extracted from select English-language patents (including US, WO, and EP) starting from 1976. Historical patent information (1869–1980) is also integrated from Beilstein and Gmelin.
