Chemical Vendor Policy

PubChem welcomes and encourages chemical vendors to provide their product information via the PubChem Compound Chemical Vendor section (e.g., see Compound ID 24848590).  This section enables researchers who use PubChem to find suppliers of the chemical substances they need.  Information can be provided using PubChem Upload after you learn how to provide your catalog.

 

To associate your information with a PubChem Compound record, you must upload your chemical substance description with a valid chemical structure description.  Structure formats like SMILES and MOL/SDF are accepted. You can also use a PubChem CID or an IUPAC InChI.

 

To keep the quality of information high for scientific researchers, a chemical vendor must follow PubChem policies.  PubChem reserves the right to remove a chemical vendor who does not comply with PubChem Chemical Vendor policies.  In addition, PubChem reserves the right to reject any content that fails to follow PubChem Chemical Vendor policies.  Please note that chemical vendors are listed in random order.  PubChem Chemical Vendor policies and guidelines are subject to change to reflect the needs of PubChem users.

 

PubChem Chemical Vendor policies (and guidelines):

1. Chemicals advertised must exist and be in stock.  [So-called virtual compounds and make-on-demand compounds are not allowed.  Users expect all content to be an existing chemical substance.  In addition, PubChem is not sufficiently funded to support many millions or billions of hypothetical chemical structures that could be made.]

 

2. An URL to the chemical vendor's home page that works and provides the chemical vendor’s contact information.  [Users expect a chemical vendor to have an official web presence that reflects the chemical vendor’s identity.  A Facebook or eBay page is not sufficient.]

 

3. An email address reflecting the chemical vendor company name.  [PubChem expects an email reflecting the chemical vendor’s identity when communicating.  In addition, PubChem needs a stable contact address for continuity purposes.  A Gmail account is not sufficient.]

 

4. The physical location of the chemical vendor must be provided corresponding to the headquarters or manufacturing facility. If the provided location is not near to the origin of the products, the product origin must be clearly stated on the company website and source description.  [Users expect to understand the origin of the products being provided.  The physical location should be verifiable in some fashion such as using Google Maps.]

 

5. An individualized web-page URL to each product advertised is strongly encouraged.  [Individualized URLs greatly assist users in getting back to the vendor website for further information on a specific product.]

 

6. Web-page URLs provided to PubChem must be in English regardless of other languages supported.  [The PubChem website is in English and users expect links from the website to also be in English.]

 

7. Products for sale must not be in violation of applicable U.S. law.  [For example, controlled substances or prescription drugs must be provided in accordance with U.S. law.]

 

8. The chemical vendor's website must be free from security violations and warnings.  [Users expect a website that does not put them at risk when ordering chemicals.]

 

9. Web links within the chemical vendor website must conform to the spirit of the above policies.

 

10. When multiple links per chemical structure are provided, the default link count visible in the 'Chemical Vendors' section will be limited. [Users expect a succinct set of links per vendor.]
