There are tens if not hundreds of chemical structure databases around at the moment. Some of them, such as PubChem, ChemExper, ChemSpider, Emolecules etc., are very useful to locate compound suppliers or to find biological/physical properties. But only two databases are currently providing synthesis or synthesis references free of charge: OrgSyn and Heterocycles. These websites are very useful for organic chemists. There is only one disadvantage: the data in these databases is limited to a few journals.
We created a freely accessible database of chemicals with synthesis references that are not limited to a few journals. Along with these synthesis references our database also contains physical properties for the listed substances.
There are currently more than 40 000 compounds and more than 45 000 synthesis references in the database.
Evidently, we are not able to compete with databases like Beilstein. Our main advantage, however - we will never make our service chargeable. Regardless of this fact, we will try to build as big a database as possible.
In addition, we would like to build the biggest database with physical properties available on the internet free of charge.
