CSD-Enterprise includes everything in the CSD-System, CSD-Discovery (plus CSD-CrossMiner), and CSD-Materials, software and application data for the Cambridge Structural Database (CSD), the world’s only comprehensive, up-to-date, and fully-curated knowledge base of small molecule crystal structures. CSD-CrossMiner allows crystal structure databases such as the Cambridge Structural Database (CSD) and the Protein Data Bank (PDB) to be simultaneously searched in terms of pharmacophore queries.

"SynOne offers search, browse, and discovery options across the entire Thieme Chemistry publication portfolio (journals, reference works, and encyclopedias) and the results are linked via a systematic and unique hierarchy of compound classes, which has been put together by chemists for chemists. SynOne is a Thieme Chemistry discovery interface which can help you find relevant and reliable high-quality publications on organic synthesis and which will present your results in context."--About page.

The CAS Source Index (CASSI) Search Tool is an online resource intended to support researchers and librarians who need accurate bibliographic information. This free resource can be used to quickly and easily look up or confirm publication titles and abbreviations, as well as CODEN, ISBN, or ISSN codes. The CASSI database contains a listing of publications indexed by Chemical Abstracts Service (CAS) since 1907.

Driven by the vast, yet largely unexplored, potential of bioactive organisms in the ocean and improvements in analytical techniques to facilitate their research, natural products scientists face an increasing need for single-source reference cataloging the current knowledge and state-of-the-science regarding marine natural products. "Dictionary of Marine Natural Products with CD-ROM" presents a comprehensive resource for more than 25,000 known natural products drawn from marine organisms.Following a similar format to the Chapman and Hall Chemical Database, this dictionary indexes each product by chemical name, CAS registry number, and compound type. Documenting all known marine natural products, each entry includes the biological source, chemical structure, physical properties, biological activity, and literature references for each compound. An accompanying CD-ROM is fully text and structure-searchable and enables unique access to this valuable resource.The editors, John Blunt and Murray Munro, both pioneers in the field, also provide an introductory monograph that describes structural compound types and marine organisms. Marine organisms offer a delicate, yet plentiful source for a vast array of novel products whose unique structural features make them suitable drug candidates, pesticides, marine anti-fouling agents, and more. "The Dictionary of Marine Natural Products Web Version" gives researchers a new tool for developing pharmaceutical and chemical applications of marine natural products.

A comprehensive structure database of natural products. Continually reviewed to keep pace with the current literature, this database is the most comprehensive source of natural product information available. Additionally each natural product is linked, via the species name, to Catalog of Life (www.catalogueoflife.org), thereby providing authoritative taxonomic information.

The DOC database contains nearly 99,000 entries comprising more than 292,000 organic compounds. It includes the following compounds: the basic fundamental organic compounds of simple structure, compounds of industrial or commercial value including currently important pharmaceuticals, pesticides, monomers, etc., Compounds frequently encountered in the laboratory as solvents, reagents or starting materials, a limited selection of the most important and well-documented natural products, important biochemicals, other compounds of particular interest because of their chemical, structural or biological properties, including many newly synthesised compounds of active research interest. DOC also covers the principal organic compounds of Se, Te, As, Sb and Bi. There is also selective coverage of organo-B and organo-Si compounds, especially those of importance in synthetic organic chemistry. DOC does not in general document isotopically labelled variants except for a few isotopically labelled drug variants used in chemotherapy or tracer work.

• Features of WebCSD include:
• Substructure searching
• Similarity searching
• Text/numeric searching (journal reference, compound name, all text)
• Reduced cell searching
• Database browsing.

Web interface to Cambridge Structural Database (CSD) without the need to install client software. Contains published crystallographic data on organic, organometallic, and metal complex structures whose 3D structures have been determined using X-ray diffraction or neutron diffraction.

Presents chemical physical and structural data on coordination compounds, organometallic compounds, the elements, simple binary and ternary compounds, and major bioinorganic compounds.

Online resource for synthetic organic chemists which provides information about the most important and useful synthetic reactions, organized primarily by reaction type. Each major component contains a critical discussion of the featured type of reaction as well as a step-by-step guide to performing it. The online version of Organic Reactions has been a regularly updated online database since 2003 and is available as either an electronic major reference work (eMRW), or a fully-featured database product with a set of advanced tools for structure/sub-structure and reaction searching.

The American Chemical Society is the leading publisher of peer-reviewed research in the chemical and related sciences, publishing 54 research journals plus Chemical & Engineering News, a weekly newsmagazine, the ACS Symposium Series, plus some reference books. Updated daily, covers 1879-present.

The ChemExper Chemical Directory displays information about chemicals (physical and chemical characteristics, structure, MSDS and more.) It contains for now over 200,000 different chemicals, 10,000 MSDS and over 10,000 IR spectra. The directory can be searched by registry number, molecular formula, chemical name or synonyms in different languages as well as by physical and chemical characteristics and combinations of those data, and also may also be searched by substructure. This web site also includes the Chemical Calculator, which calculates the molecular formula, molecular mass, exact mass, elemental analysis and plots the isotopic distribution graph; enter molecular formula, atoms, isotopes as well as groups; and the OSIRIS Property Explorer, which lets you draw chemical structures and calculates on-the-fly various drug-relevant properties whenever a structure is valid. Prediction results are valued and color coded. Properties with high risks of undesired effects like mutagenicity or a poor intestinal absorption are shown in red whereas a green color indicates drug-conform behaviour.
