Chemical Vendor Search (US version)

Chemical Vendor Search

Search a CAS number (or chemical name) in the above box to automatically find results from verified, high-quality chemical vendors.

This is the US version of the Chemical Vendor Search.
The UK version is here.

You can search direct from the URL bar in Chrome, by typing "cvs" and then Tab!
Go to "Settings" -> "Other search engines" -> "Add". Then, type "cvs" as the keyword, and copy the following as "URL with %s in place of query":

Search tips:

  • CAS numbers give more accurate results than chemical names.
  • If your preferred vendors don't show up, you may wish to check their sites separately. Products may not appear if their pages are not indexed by Google.
