Database chemical prices

Factual databases may provide the electronic version of printed catalogs on chemical compoimds. The catalogs of different suppliers of chemicals serve to identify chemical compounds with their appropriate synonyms, molecular formulas, molecular weight, structure diagrams, and - of course - the price. Sometimes the data are linked to other databases that contain additional information. Structure and substructure search possibihties have now been included in most of the databases of chemical suppliers. [Pg.240]

CHEMCATS is an online database accessible through Chemical Abstracts that contains over 13 million commercially available componnds, inclnding pricing information when available from snppliers and for many also direct hyperlinks to snppliers sites. CHEMCATS is routinely updated with new information provided by snppliers already in the database and with new snppliers and/or catalogs. This is another commercial prodnct, bnt there is no up front fee pricing is based on pay as yon go and can be accessed through STN Easy (http //stneasy.cas.org/). [Pg.264]

The Hbrary can easily be reused every time educts of this chemical class are needed. The entire educt Hbrary is stored as a database, including structures, descriptors, mapping coordinates, cluster memberships, etc., and availabiHty information such as suppHer or price. The chemist can retrieve optimized subsets of different sizes from this database. [Pg.594]

The Available Chemicals Directory (ACD) is available through http //www.chemweb.com (see above) along with a wide range of other useful databases for a conunercial price. [Pg.161]

Available Chemicals Directory MDL database Is a chemical database providing access to pricing and supplier information for more than 400,000 research-grade and bulk chemicals. Available at http //www.mdl.com. Accessed March 28. 2007. [Pg.137]

An important factor in the progress of bioinformatics has been the constant increase in computer speed and memory capacity of desktop computers and the increasing sophistication of data processing techniques. The computation power of common personal computers has increased within 12 years approximately 100-fold in processor speed, 250-fold in RAM memory space and 500-fold or more in hard disk space, while the price has nearly halved. This enables acquisition, transformation, visuahsation and interpretation of large amounts of data at a fraction of the cost compared to 12 years ago. Presently, bioanalytical databases are also growing quickly in size and many databases are directly accessible via the Internet One of the first chemical databases to be placed on the Internet was the Brookha-ven protein data bank, which contains very valuable three-dimensional structural data of proteins. The primary resource for proteomics is the ExPASy (Expert Protein Analysis System) database, which is dedicated to the analysis of protein sequences and structures and contains a rapidly growing index of 2D-gel electrophoresis maps. Some primary biomolecular database resources compiled from spectroscopic data are given in Tab. 14.1. [Pg.605]

With standard networks and moderately priced workstations now available, distributed systems could become popular research environments in the chemical/ pharmaceutical industry. Distributed systems typically allow the user to do interactive and routine tasks such as editing and report preparation on a workstation with its quick response time. Further, they allow the user to send computational or database operations across a network to a mini/mainframe that acts as a server. This architecture offers the end-user scientist the best of all worlds, immediate response for common operations and quick access to centralised chemical-scientific database operations. [Pg.108]

For the manufacture of vinyl chloride, assemble a preliminary database. This should include thermophysical property data, MSDSs for each chemical giving toxicity and flammability data, and the current prices of the chemicals. [Pg.105]
