SciFinder and SciFinder-n

Introduction

SciFinder is the online version of Chemical Abstracts, Medline and other resources.  In it you can search articles, patents, conferences, books and dissertations in chemistry, medicine, and related disciplines, by substance name or formula, structure, reaction, research topic and author.  Full text is available through the "Other Sources" link. 

The University of Iowa now has access to this index through two interfaces, SciFinder and SciFinder-n. 

Registration is required before the first use.  If you have already registered for SciFinder, your username and password will work for either one. 

Access

The links below work from anywhere, but you must use them to access either interface from off-campus. 

Both interfaces search the same information but are quite different.   

  • SciFinder   This classic version has been available since 2008 and has an older architecture.  It has system limits so you have to be more precise in searching.  
  • SciFinder-n   This interface has just become available.  It has a more modern architecture so it allows more flexible searching, has relevancy ranking,  and better functionality via mobile devices.  It also has no system limits, renders structures in standard conventions and allows you to combine reference and structure searches.  It includes these new tools: PatentPak, MethodsNow and Retrosynthesis Plan.   

SciFinder Registration

If this is your first time using SciFinder, you must register for an account. You must be on campus and use your University of Iowa email address (@uiowa.edu) to register. After you submit your registration form, CAS will send you an e-mail with instructions for completing the registration process. This email should arrive within 30 minutes, if not, check your spam folder.

If you have followed the instructions above, but you're having problems registering for a SciFinder account, please contact help@cas.org or 800-753-4227.
