Chemical Vendor Search (US version)

Click on the image above, and paste a CAS number or chemical name to automatically search for results from verified, high-quality chemical vendors.

The UK version of the Chemical Vendor Search is here.

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.
