Chemical Abstracts Service - CAS
CAS is the only organization in the world whose objective is to find, collect and organize all publicly disclosed substance information. We build and maintain the world's largest collection of molecular substances, reactions, and related content that is vital to the work of researchers.
ChemSpider
"ChemSpider is a free chemical structure database providing fast access to over 63 million structures, properties, and associated information. By integrating and linking compounds from ~280 data sources, ChemSpider enables researchers to discover the most comprehensive view of freely available chemical data from a single online search. It is owned by the Royal Society of Chemistry."
eMolecules
eMolecules empowers researchers to explore uncharted chemical and biological spaces and deliver more efficient drug-discovery programs.

CDC | NIOSH Pocket Guide to Chemical Hazards
General industrial hygiene information on several hundred chemicals/classes. Presents key information: NIOSH recommended exposure limits, OSHA permissible exposure limits, and NIOSH immediately dangerous to life and health values (IDLH)--with linkouts to these databases. Also physical properties, personal protection recommendations, incompatibilities and reactivities, exposure routes, symptoms and more.
IPCS Inchem: Chemical Safety Information
Rapid access to internationally peer reviewed information on chemicals commonly used throughout the world, which may also occur as contaminants in the environment and food. It consolidates information from a number of intergovernmental organizations whose goal it is to assist in the sound management of chemicals.

Los Alamos National Laboratory | PERIODIC TABLE OF ELEMENTS
Originally this online resource was created by Robert Husted at Los Alamos National Laboratory during his time as a Graduate Research Assistant, circa 1992. It was given a face lift during 2002/2003 by Mollie Boorman, then a student working at the Laboratory. In 2011, it was again re-designed and updated by Maida Trujillo of the Chemistry Division web team with technical and writing assistance from Dave Hobart and Josh Smith, both of Chemistry Division.
Royal Society of Chemistry | Periodic Table
The Royal Society of Chemistry's interactive periodic table features history, alchemy, podcasts, videos, and data trends across the periodic table. Click the tabs at the top to explore each section. Use the buttons above to change your view of the periodic table and view Murray Robertson’s stunning Visual Elements artwork. Click each element to read detailed information.

PubChem Compound The PubChem Compound Database contains validated chemical depiction information provided to describe substances in PubChem Substance. Structures stored within PubChem Compounds are pre-clustered and cross-referenced by identity and similarity groups.
Pubchem Substance
The PubChem Substance Database contains descriptions of samples, from a variety of sources, and links to biological screening results that are available in PubChem BioAssay. If the chemical contents of a sample are known, the description includes links to PubChem Compound.
RefSeq: NCBI Reference Sequence Database
A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.
What is the National Center for Biotechnology Information (NCBI)
The National Center for Biotechnology Information (NCBI), a division of the National Library of Medicine (NLM) at the U.S. National Institutes of Health, is a leader in the field of bioinformatics; it studies computational approaches to fundamental questions in biology and provides online delivery of biomedical information and bioinformatics tools. NCBI hosts approximately 40 online literature and molecular biology databases—including PubMed, PubMed Central, and GenBank—that serve millions of users around the world.
