Getting Started with SciFinder

scifinder logo


  • The new interface, SciFinder-n, is now available to UT Austin users.  Try it out whenever you like - it's very different and has multiple added features and tools not included in the old version.  The classic interface will probably be retired in mid-2022.
  • Due to the COVID pandemic, CAS has lifted IP address restrictions until January 31, 2022, and logging in via UT's proxy server with your UT EID and password plus Duo is not required at present.  If you don't plan to use links to full text articles, you can go directly to SciFinder without using the proxy.  You still need your personal SciFinder ID and password to log in. 

Who can use SciFinder?

Individuals affiliated with UT-Austin may register for a personal SciFinder account and use it from any computer that is connected to or proxied through the campus network, including library workstations.  Authorized persons include:

  • Currently enrolled students
  • Currently appointed faculty and staff
  • Retired and emeritus faculty and staff (with official retiree status)
  • Currently appointed postdocs
  • Official visiting scholars (with valid faculty/staff UT EID and email address)

These types of individuals are not allowed to register for or use SciFinder:

  • Alumni and former students (1 semester after departure)
  • Former faculty, staff; former postdocs
  • Unofficial visitors (without faculty/staff UT EID or utexas email address)
  • Library Courtesy Borrowers
  • General Public

Terms of Use

Use of SciFinder must be for educational and academic research purposes only. Commercial use - including patentability searching - on behalf of any profit-making entity, regardless of one's personal status at UT, is not permitted. Users must agree to these terms when connecting to the resource. CAS actively monitors and reports suspect activity, and violation of the terms of use may result in loss of access.

Coming from another institution?

If you're new to UT but used SciFinder at a previous institution, your old account won't work here.  Create a new one by registering above with your email address.  TIP:  If your web browser "remembers" and automatically enters your old SciFinder login ID and password, you'll have to clear that out and update it with your new one.

Access from Off Campus:  Proxy vs VPN

[Note:  CAS has temporarily lifted IP restrictions due to COVID, and a proxy connection is not required at present.]

To get to all our licensed resources while outside the campus network, you must use our Proxy Server to establish a session that carries a recognized UT Austin IP address.  Two methods:

  • Follow a link from any Library web page, catalog record or database directory, and enter your UT EID and password when prompted.  Multifactor authentication with Duo is then required.
  • Bookmark this link in your browser:

VPN will not work for this purpose, and will interfere with a proxy connection.  Exit VPN and proceed through your local network to establish a proxied connection via links on the Libraries' pages.

What's in SciFinder?

SciFinder is the best place to start your search for research-level chemical information. It provides integrated access to these Chemical Abstracts Service (CAS) databases, plus Medline:

SciFinder vs Reaxys

SciFinder and Reaxys (incorporating Beilstein and Gmelin) are complementary resources, and although there is some overlap the two are quite different in their respective literature coverage, and the ways they register compounds and index reactions. It's advisable to consult both databases for the most complete coverage of compounds, reactions, and properties.


Off Campus access easier during COVID situation

CAS has temporarily lifted the IP address restrictions during the pandemic work-from-home period, until January 2022.  This means that you don't need to log in via the Libraries proxy server, but you will still need your SciFinder ID and password.  However, links to full text licensed content from within SciFinder won't work unless you're in a proxied session.

SciFindern at UT

SciFinder account holders at UT Austin have access to both the original and new versions of SciFinder.  CAS is currently rolling out a new interface called SciFindern (yes, that's a superscript "n").  The "classic" SciFinder Web interface is no longer being enhanced, although the bibliographic, substance and reaction data are fully up to date.  There is no firm retirement date for the classic version at this time, but it will probably go away in 2022.
