ChemSpider is home to over 128 million chemical structures and attracts researchers, in their millions, from around the world. In a single day, tens of thousands of research chemists use the ChemSpider tools and resource to support their work. You can position your company in front of them and broadcast your message to the whole ChemSpider community.
With hundreds of thousands of chemists around the world visiting the site daily your company has an opportunity to expose your products to users and catalyze potential sales.
As a chemical vendor your organization has an opportunity to be listed as a data source containing the chemicals that you offer commercially. Each organization has a dedicated webpage that you can manage and update (see here for an example). For a list of data sources and example organizations presently listed on ChemSpider please visit the Data Sources page for more information.
You will also be listed as a vendor on the ChemSpider page for each structure in your catalogue.
Please note that we have some requirements to be added as a vendor in ChemSpider:
If you meet all of the above criteria, please continue reading for more information about how to submit your catalogue and our formatting requirements.
To discuss your requirements and pricing options please email advertising-at-rsc.org.
We prefer to receive catalogues as SDF files wherever possible, but we also accept Excel spreadsheets (.xls, .xlsx, .csv) that contain all of the required information. Please carefully read the requirements below. If any of the required information is missing, we will be unable to process your catalogue. Please note that we do not accept virtual or prophetic compounds.
If this data is missing, we will be unable to process your catalogue.
Data quality is important to us. We run all files through a series of checks to filter out common structural errors. This means that the final count of products in your listing may be slightly lower than in the file you have supplied.
The following information will be removed:
Ionic structures drawn with covalent bonds or where the counterion is drawn as an elemental metal are removed or standardised. We also apply other standardisation and structure tidying, which helps users find your information by making sure it is mapped to the best page.
At the end of the deposition process, we will send you SDF files containing the structures which were filtered out.
Please note that we cannot accept listings which do not contain machine-readable depictions of chemical structures. We can only accept submissions based on mol/SDF, InChI or SMILES representation. We cannot process files that only contain lists of proprietary registry numbers or other identifiers.
When you have a catalogue file ready for deposition, please send it to us by email (ChemSpider-at-rsc.org.). If your file is too large to email, contact us. For larger files we can supply FTP details or arrange to download it from your site.
Every Chemical Vendor on ChemSpider has a Data Source profile. Click here for an example page. When we first deposit your catalogue to the site, we will create a profile for you. This is the main source of information about your company on ChemSpider, so it is worthwhile to take some time to think about how you would like it to read.
Try to keep the description short and avoid complex formatting – remember the user can follow the link to your website for further information. When you hover over your name on a record page, this description will appear in a pop-up box; this display can only show a small amount of content.
Be sure to send us logo for your profile page. Logo files may be supplied as JPG, GIF or PNG files, and cannot be larger than 50kb in size.
If later on you decide you’d like to change the wording of your description, or if you want any other changes to your Data Source profile, drop us an email (ChemSpider-at-rsc.org.) and we’ll make the changes for you.
When you have an updated catalogue available, please email advertising-at-rsc.org. to discuss the process for renewal. We are able to process updates on a quarterly basis to make sure your listings are up-to-date.
In order to make sure that our Chemical Vendors list remains accurate and up-to-date, we need to receive catalogue updates at least once a year. If the catalogue you have listed on our site is more than a year old, we may at our discretion contact you to request an updated version. As a last resort, we may remove badly out-of-date listings from our site entirely – so please remember to contact advertising-at-rsc.org. to discuss your renewal.
We run all files through a series of checks to filter out common structural errors and to make sure that the structures supplied are compatible with the ChemSpider data model. This means that the final count of products in your listing may be slightly lower than in the file you have supplied. Usually ≤5% of structures will be filtered out. This can vary depending on the kinds of products you are selling, and the choices made in depicting your structures. After depositing your catalogue we will send you files containing the structures which were filtered out so that you can review them.
No – without structural information (structures in an SDF file, or SMILES or InChI in an excel file) we cannot process your catalogue. Other identifiers such as registry numbers do not describe the structure of the compound; they cannot act as a substitute for this information.
Yes, we can process your catalogue without synonyms or registry numbers. However, if you do have this information available please do include it in your file as this can help people discover your listing.
Please email advertising-at-rsc.org. and we would be happy to arrange this
We are usually able to upload catalogues within one week, however during busier times it may take up to a month. This may vary depending on the size of your file – if you have millions of compounds, it will normally take longer. Please feel free to inquire after your catalogue if it has not been added to the site within one month.
We cannot currently provide you with structure files from a list of compound names.
We do not currently provide solutions for chemical web stores.
Send all questions to ChemSpider-at-rsc.org., where a member of our team will pick them up. Please do not directly contact individual team members – this could cause a delay in your question being responded to.
