SciFinder Basics

ALERT:  Due to the COVID pandemic, CAS has lifted IP address restrictions until October 18, and logging in via UT's proxy server is not required at present.  You still need your personal SciFinder ID and password.

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

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.  To do this follow a link from any Library web page or database directory, and enter your UT EID and password when prompted. [Note:  CAS has temporarily lifted IP restrictions due to COVID until October 18, 2020, and a proxy connection is not required at present.]

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

Other Sources of Help and Support

What's in SciFinder?

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


Note that UT does not subscribe to two additional data components within SciFinder, PatentPak and ChemZent.

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 October 18, 2020.  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.

Will UT be getting SciFindern?

CAS is currently rolling out a new SciFinder interface called SciFindern (yes, that's a superscript "n").  The "classic" SciFinder Web interface is no longer being developed with enhancements or new datasets, although the bibliographic, substance and reaction files are fully up to date.  There is no retirement date for the classic version at this time.  At some point in the future it's likely that UT System will have to migrate to the new version, but we have no firm plans to do so at this time.
