Online Chemical Catalog

Welcome to our on-line compounds catalog. You can search for the products by IUPAC and trade name, part of name, CAS registry number, product number, molecular formula, structure or substructure. Catalogs in SDF format (ChemFinder, etc.) and DB format (ISIS Base) are also available upon request.

Compound Libraries and Building Block

We offer building blocks for combinatorial chemistry and a library of drug-like small molecules for drug discovery research. Our database contains more than 2000 novel compounds for the above applications and general synthetic use. Most of these compounds are exclusive and not available in other companies’ catalogues. The collection of organic intermediates includes the following classes of compounds: piperazines, coumarins, pyridines, imidazole, thiazoles, indoles, aminoacids, etc.

All our compounds are synthesised in-house using classical organic procedures and are subject to rigorous quality control procedures. The minimum purity of all compounds is 90% (but 95% on average). Purity is normally checked by 1H NMR (Bruker 500 MHz) but, if this is inconclusive then we would proceed to 13C NMR, elemental analysis and mass spectroscopy, using whichever technique is most suitable for the compound being studied. As all of the chemistry is our own, resynthesis is continually carried out to replenish stocks.

To help you find our products via online catalog, we offer various search methods.

• Search by Keyword

You can search for the products you require by chemical name (e.g. 2-morpholin-4-yl-6-thianthren-1-yl-pyran-4-one), part of chemical name (e.g. thiomorpholine), molecular formula (e.g. C17H12F4O4), CAS registry number (e.g. 753391-71-8), MDL Number (e.g. MFCD00014874), EINECS (e.g. 205-529-2) or product number (e.g. EC-000.2036).

• Search by Structure

The «Search by Structure» feature is used to locate products by chemical structure or substructure. Simply draw a structure or structure fragment in the editor provided and click the search button. To search the Exclusive Chemistry catalog by drawing structures on-line click Structure Search.

Frequently Asked Questions

The open, interactive FAQ service provides a variety of additional information about our products and services. Please, check the list to see if your question can be answered quickly.

1. What is the purity of your compounds?

The minimum purity of all compounds (externally acquired & in-house) is 90% minimum, and 95% on average. Purity is tested by NMR for 100% of the compounds (available free of charge upon request). LC-MS is ised as supplementary control.

2. What is the origin of the compounds?

Compounds come from two main sources. The largest collection is in-house synthesized compounds. Exclusive Chemistry Ltd also has collection of compounds acquired externally from contract chemists and universities, located in Russia.

5. How long does it take to deliver the compounds?

It takes 1-2 weeks to deliver compounds (depending on the quantity of compounds) after we have received an official purchase order.

7. What is the price range?

The price for compounds from our collection varies depending on the quantity, weight, and format in which you want to receive the compounds.

8. How often do you replenish your collection?

Our compound collections are updated every few month.
