Chemical Vendor Search (US version)

Chemical Vendor Search (US version)

I made this web tool to expedite buying chemicals from trusted, high-quality sources.

Paste a CAS number or chemical name at the URL below (CAS numbers work better) to automatically search for results from verified, high-quality chemical vendors.

Chemical Vendor Search

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.
  • The UK version of the Chemical Vendor Search is here.

Don't see your favourite vendor in the list? .
