SciFinder
SciFinder is a paid database developed and offered by Chemical Abstracts Service , which has been available as a web-based version since 2008 and can now also be accessed via smartphone. The previous program was called Messenger . Its query language could only be used satisfactorily with in-depth knowledge of the program.
The database contains (as of July 2019) data on over 154 million defined chemical substances , over 68 million sequences and more than 116 million reactions . Around 35,000 substances are added every day and around 5.8 billion data records are available for the registered substances. There are data on melting point , boiling point , density , refractive index , magnetic and electrical properties and other information. Spectrum data of the usual methods can be found: NMR, protons and other nuclei , IR , MS , ESR , UV-Vis etc.
In addition to substance data, the database contains summaries of over 50 million scientific articles, the patents of 63 patent organizations and sources of supply for commercially available substances.
SciFinder is designed for professional use by chemists and other natural scientists / engineers at universities , companies and authorities . There are search options using keywords (Research Topic), which can be combined as required, author names, company names, document identifiers and journal names . Substance information (e.g. physical properties, spectra, synthesis, applications, commercial sources) can be searched for using structural formulas and substructures that can be generated using an integrated editor or imported from a locally saved CXF file. There is also the possibility of using empirical formulas , CAS numbers or substance properties such as boiling point, melting point, density, refractive index, etc. (although range specifications are also possible) as a search term. The lists of search results generated in this way can be further refined using the same operators . Several search lists can be combined. In addition, patents of the most important patent organizations can be searched, also using Markush formulas .
