Most Popular Chemcials Databases
« on: August 03, 2017, 05:12:57 AM »
Hope the databases listed below will help you guys find what you need:

Biomolecule Binding Database

The BindingDB is a public, web-accessible database of measured binding affinities for biomolecules, genetically or chemically modified biomolecules, and synthetic compounds.


Chemical Entities of Biological Interest (ChEBI) is a freely available dictionary of molecular entities focused on "small" chemical substances. ChEBI draws its information from two main sources: Integrated Relational Enzyme Database of the EBI and the Kyoto Encyclopedia of Genes and Genomes.


ChemACX is a comprehensive online catalog containing current product information from 405 leading chemical supplier catalogs such as Sigma Aldrich, Fisher Scientific, Acros, Alfa Aesar, Lancaster, Novabiochem and TCI America. ChemACX provides rapid ordering information for over 352,300 unique chemical compounds, over 733,100 products, and is updated bi-annually.

Chemazone - Organic Chemicals for R&D

Are you looking for organic chemicals for research and development and cannot find them commercially available anywhere? The Chemazone website contains more than 2,000,000 readily available synthetic organic compounds.


Chembank is a freely available collection of data about small molecules and resources for studying their properties, especially relating chemistry to biology, and a suite of informatics tools and databases aimed at promoting the development and use of chemical genetics by scientists worldwide. Chembank currently has a database of about 2000 compounds, with SMILES strings, chemical structures and biological activity. Soon other files will be downloadable.

ChemExper Chemical Directory

The ChemExper Chemical Directory displays information about chemicals (physical and chemical characteristics, structure, MSDS and more.) on the Internet in order to create a world-wide database. It is free to consult and easily accessible over the Internet on any computer using a web browser. The ChemExper Chemical Directory contains for now over 200,000 different chemicals, 10,000 MSDS and over 10,000 IR spectra.


CambridgeSoft maintains ChemFinder, a remarkably efficient Internet search engine, which searches for information on specific compounds by name, formula, CAS registry number, and molecular weight.

Chemical Abstracts Service

CAS is the producer of Chemical Abstracts, SciFinder, SciFinder Scholar, and also operates STN International and the web based STN Easy online searching services which provide access to chemical and scientific information from databases covering topics such as chemistry, engineering, patents, medicine regulatory data and business. CAS databases provide access to over 25 million documents, 26 million chemical substances and 56 million sequences.

Chemical Catalog by Exchemistry

An online catalog of chemicals searchable by Chemical Name, Product Number, CAS Registry Number and Molecular Formula. Chemical custom synthesis of compounds that cannot be found in the major catalogues (Sigma-Aldrich, Acros Organics, etc) is also available.

Chemical Structure Lookup Service

Look up whether a structure occurs in any of tens of different databases, both public and commercial. Currently loaded pointers to: over 39 million entries from more than 80 databases, representing more than 27 million unique chemical structures.

Chemicals for R&D

The R&D Chemicals is a free service that allows to find a chemical by its molecular formula, IUPAC name, smiles, common name, CAS number, catalog number, substructure or physical characteristics as well as chemical suppliers.
Examples of a textual query: Extrasynthese, Jrd Fluorochemicals, Frinton Laboratories.


ChemIDplus provides access to structure and nomenclature information for the identification of chemical substances cited in NLM (National Library of Medicine) databases. The database contains over 380,000 chemical records, of which over 263,000 include chemical structures. ChemIDplus Lite is available for Name and RN searching without the need for plugins or applets.


ChemSink is a chemical reaction database. It is a place for anyone interested in chemical synthesis to come and discuss their successes and failures with specific chemical reactions. The chemsink database is free to download, alter, and use.

ChemSpider - Database of Chemical Structures

ChemSpider is a chemistry search engine. It has been built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and making it available to everybody, at no charge. ChemSpider is a value-added offering since many properties have been added to each of the chemical structures within the database - structure identifiers such as SMILES, InChI, IUPAC and Index Names as well as many physicochemical properties.

ChemSub Online

ChemSub Online is a free web-based database which allows you to retreive information for over 237,000 chemical substances of which 138,000 include chemical structures.
