SciFinder Setup: Accessing SciFinder

Instructions for installing either the web or client version of SciFinder (Chemical Abstracts tools) for PC and Mac.


SciFinder is a search interface for Chemical Abstracts, the CAS Registry File, and Medline.  Reaction searching and a sophisticated structure searching are capabilities of the software. Links to full text services, commercial suppliers, and regulatory information are included. Abstracts are detailed and, since 1999, include the reference lists for the articles abstracted.

Using ChemDraw with SciFinder

See the tab in this guide for "ChemOffice Pro", which includes ChemDraw. You can draw chemical structures or reactions and load them into SciFinder for searching in latter. See that tab for instructions about how to set up ChemDraw for this purpose; scroll down to "Using ChemDraw with SciFinder".

Search Tips

  • Collaborate on searching with colleagues in your research group
  • If you generate a large answer set, then use Refine, Analyze and/or Categorize to filter and focus-in on items of interest
  • When performing a Substance Identifier search, enter more than one Substance Identifier (up to 25 may be entered)
  • Use the Quick Views (the small handheld magnifying glass icon) to preview information about references and substances.
