Nessa the Chemist


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.

To search directly from the omnibar in Chrome, add a new search engine 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.
