Reaxys includes Substance Property Data and Spectral Data abstracted from literature back to 18th century
SciFinder-n is the new interface for the classic version of SciFinder. If you have already registered for Classic SciFinder, that login should work for SciFinder-n.
Web interface to Cambridge Structural Database (CSD). Contains published crystallographic data on organic, organometallic, and metal complex structures whose 3D structures have been determined using X-ray diffraction or neutron diffraction. Includes substructure search, similarity search, text/numeric search, reduced cell search, and browse capabilities.
CRC Handbook of Chemistry and Physics by
Publication Date: 2019
The CRC (Chemical Rubber Company) Handbook of Chemistry and Physics is the standard book containing tables, definitions, and charts used in chemistry, chemical engineering, and physics. The Web version allows the user to create spreadsheets, and it cross-links to all tables on any compounds thereby increasing its usefulness.
Owned by Royal Society of Chemistry, ChemSpider includes more than 26 million unique molecules from over 400 data sources.
PubChem is an open chemistry database at the National Institutes of Health (NIH). “Open” means that you can put your scientific data in PubChem and that others may use it. 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.
NIST Data Gateway
Easy access to NIST scientific and technical data. These data cover a broad range of substances and properties from many different scientific disciplines. Search by specific keywords, properties and substances across a collection* of NIST scientific and technical databases.
Dictionary of Natural Products
The online version of the Dictionary of Natural Products is a structured database holding information on chemical substances. It includes descriptive and numerical data on chemical, physical and biological properties of compounds; systematic and common names of compounds; literature references; structure diagrams and their associated connection tables.
Chemical Name Reactions
Chemists often refer to a particular type of reaction by name. Often, the reaction is given the names of the chemists who discovered, improved or promoted that particular reaction. Examples: Diels-Alder reaction, Claisen rearrangement, Sharpless epoxidation.
I have the name of a reaction; how do I find out what the chemical reaction is?
Some good starting points:
online comprehensive collection of important synthetic reactions, including critical discussion, and tables of all published examples of the reactions.
