Reaxys
Reaxys is a reference source on chemical properties, compounds, and reactions supporting research in organic and inorganic chemistry.

Reaxys Support Center
This page contains a number of tutorials on using Reaxys. You can also navigate to a Training page that provides information such as the Reaxys Reference Guide and how to create structure drawings.

SciFinder-n
A database provided by the Chemical Abstracts Service (CAS), full of chemical and bibliographic information that covers many scientific and biomedical fields, with an emphasis on chemistry.

SciFinder-n Training and Tutorials
These on-demand SciFinder-n training resources are short, targeted materials, organized by search type.

Scopus
Scopus is a large abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings. Delivering a comprehensive overview of the world's research output in the fields of science, technology, medicine, social sciences, and arts and humanities, Scopus features smart tools to track, analyze and visualize research.

To learn more about logging into Scopus, see this guide.
Knovel
A library of full-text content relating to all fields of engineering, science, and industrial safety.

PubChem
Open chemistry database at the National Institutes of Health (NIH). PubChem mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. We collect information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others.
Inspec Archive
Over 870,000 searchable records that cover 70 years of international scientific literature in physics, electrical engineering, and computer science from 1898-1968.
PubMed
The PubMed database contains more than 38 million citations and abstracts of biomedical literature. It does not include full text journal articles; however, links to the full text are often present when available from other sources, such as the publisher's website or PubMed Central (PMC).
Google Scholar
With an OSU login, the Google Scholar interface allows users to search library holdings and peer-reviewed articles.

Cambridge Structural Database
The Cambridge Structural Database is compiled and distributed by the Cambridge Crystallographic Data Centre (CCDC). The database provides access to structural chemistry data. Please see the following update from Cambridge Structural Database to update to the new 2023 version of CSD.
ChemDraw
ChemDraw is a scientific productivity suite designed for anyone related to the fields of chemistry, biochemistry, and microbiology. Users can draw chemical structures and reactions, as well as biological objects and pathways, and organize and search through multiple documents and collections of molecules. See instructions in the More Info section below for access.

Please send a request to cas-help@okstate.edu for access to ChemDraw.

ChemSpider
ChemSpider is a free chemical structure database providing fast access to over 120 million structures, along with properties and associated information. By integrating and linking compounds from hundreds of high quality data sources, ChemSpider enables researchers to discover the most comprehensive view of freely available chemical data from a single online search.
Crystallography Open Database
Open-access collection of crystal structures of organic, inorganic, metal-organic compounds and minerals, excluding biopolymers
Open Reaction Database
The Open Reaction Database (ORD) is an open-access schema and infrastructure for structuring and sharing organic reaction data, including a centralized data repository. The ORD schema supports conventional and emerging technologies, from benchtop reactions to automated high-throughput experiments and flow chemistry. Our vision is that a consistent data representation and infrastructure to support data sharing will enable downstream applications that will greatly improve the state of the art with respect to computer-aided synthesis planning, reaction prediction, and other predictive chemistry tasks.
ZINC
ZINC is a free database of commercially-available compounds for virtual screening. ZINC contains over 230 million purchasable compounds in ready-to-dock, 3D formats. ZINC also contains over 750 million purchasable compounds you can search for analogs in under a minute.
