"The online version of the critically acclaimed Encyclopedia of Reagents for Organic Synthesis has rapidly become the definitive reference source for reagents used in organic synthesis. e-EROS allows chemical structure, substructure and reaction searching straight from a chemist's desktop. It contains a database of around 50,000 reactions and around 3800 of the most frequently consulted reagents and is fully searchable by structure and substructure, reagent, reaction type, experimental conditions etc. and allows sophisticated full text searches. Each entry highlights the various uses and characteristics of each reagent, with illustrative examples of its use and is preceded by valuable information concerning physical data, solubility, form supplied in, purification, and where relevant, preparative methods and with literature references to key review articles and seminal papers.
For all scientists concerned with the development of new drugs, the print version of the standard work "the Negwer" is now availabe online. The search tools include text, structures and compound classes. The eighth edition of the Negwer compiles more than 16.000 chemically unique drugs with more than 125.000 synonyms. The organo-chemical drugs are arranged by increasing molecular formulas. Information included: an own consecutive number, the molecular formula, the Chemical Abstracts Service index number (CAS number), the structural formula, references, the synonyms used to identify the drugs (names adopted by certain institutions, common trivial names, names adopted by manufacturers, experimental names, abbreviations; and, marked with asterisks, the nonproprietary names proposed by the WHO), characterization and therapeutic use. More information about these features are given below. The group index (for finding drugs related to each other chemically or pharmacologically), the CAS number index, and the index of synonyms facilitate working with the Negwer.
