Synthesis - definition of synthesis by The Free Dictionary

We supply building blocks for combinatorial chemistry and intermediates for organic synthetic chemistry. Our major products include the kinds of compounds that cannot be found in the major catalogues, such as boronic acids, heteroaromatic acids, amines (primary and secondary) and aldehydes.

ChemSynthesis - Chemical Database

DTP maintains a repository of synthetic compounds and pure natural products that are available to investigators for non-clinical research purposes. The Repository collection is a uniquely diverse set of more than 200,000 compounds that have been either submitted to DTP for biological evaluation or, in some cases, synthesized under DTP auspices. Samples obtained from the NCI/DTP Open Chemicals Repository are available at no cost except for shipping charges. Importantly, investigators should note that chemical structures of these substances are those assigned by the originator of the material and in most cases, the compounds have not been analyzed by DTP for accuracy of structure or for the purity of the sample. Potentially available compounds can be searched by name or NSC number using the . The availability of some samples may be limited by current inventory.

Organic Syntheses - Wiley Online Library

Organic Syntheses describes checked and edited experimental procedures, spanning a broad range of synthetic methodologies, and provides chemists with a compendium of new or little known experimental procedures which lead to useful compounds or that illustrate important new developments in methodology. For every procedure, safety warnings are presented along with detailed descriptions for the preparation, purification, and identification of the compound in question. Additionally, special reaction conditions are detailed, along with the source of reagents, helpful waste disposal guidelines, discussions of results, references to the primary literature, and an appendix of nomenclature and registry numbers.
