“The CASSI Search Tool is a free resource that can be used to quickly and easily look up or confirm publication titles and abbreviations in an accessible electronic format. It is provided by CAS as a public service. The CASSISM database contains a listing of publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications. The database will be updated annually and was last updated in December 2009.”
ChEMBL is a database of bioactive drug-like small molecules , it contains 2-D structures, calculated properties (e.g. logP, Molecular Weight, Lipinski Parameters, etc.) and abstracted bioactivities (e.g. binding constants, pharmacology and ADMET data).
ChemWeb.com provides access to the information chemists need to enhance their research, product development, self-development, education, and/or their businesses in Chemistry and related disciplines. Easy access to abstracts, papers, journals, books, conferences news, forums and the Alchemist newsletter makes ChemWeb.com powerful and useful site.
SRS is the Environmental Protection Agency's central system for information about substances that are tracked/regulated by EPA or other sources. It is the authoritative resource for basic information about chemicals, biological organisms, and other substances of interest.
Espacenet which provides access to worldwide patent information. Patents by member states of the European Patent Office and the World Intellectual Property Organization are included. Years of coverage and availability of full text and images vary by country.
The ExPASy (Expert Protein Analysis System) proteomics server of the Swiss Institute of Bioinformatics (SIB) carry out the analysis of protein sequences and structures as well as 2-D PAGE (Disclaimer / References / Linking to ExPASy)
"Each month a new molecule will be added to the list on this page. The links will take you to a page at one of the Web sites at a University Chemistry Department or commercial site in the UK, the US, or anywhere in the world, where useful (and hopefully entertaining!), information can be found about a particularly interesting molecule."
The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment. This database provides thermochemical, thermo-physical, and ion energetics data on over 40,000 compounds.
