WWW Chemistry Guide - the directory and search engine of chemistry related resources on the Internet. Our search engine allows you to search the contents of more than 250 website. It searches only the sites we specify, bypassing a lot of the junk. We are only looking for the sites with the best information, resources, design and navigation. Only a small percentage of the thousands of chemistry web sites meet those criteria.

ChemSynthesis is a freely accessible database of chemicals. This website contains substances with their synthesis references and physical properties such as melting point, boiling point and density. There are currently more than 40,000 compounds. And more than 45,000 synthesis references. You can start browsing our database using the links below. Journal of the American Chemical Society.

Custom synthesis of peptides for research and development and therapeutic purposes. GPCR Ligands, Kinase Modulators, Ion channel, Protease Inhibitors and others targeted libraries. Chemical custom synthesis of novel and rare. Organic compounds at the gram and kg scales. Synthetic organic compounds designed for high throughput screening and hit-to-lead programs. Compounds for organic chemistry, combinatorial chemistry and lead optimization projects. Synthesis of monosaccharides, oligosaccharides.

Combinatorial chemistry contrasts with the time-consuming and labor intensive methods of traditional chemistry where compounds are synthesized individually, one at a time. While combinatorial chemistry is primarily used by organic chemists who are seeking new drugs, chemists are also now applying combinatorial chemistry to other fields such as semiconductors, supe.
