Our default chemical supplier is Sigma-Aldrich, which has punch-out catalogs in both the HHMI P2P and HMS B2P purchasing systems. Questions re: pricing and products can be referred to 508-238-9865.

For drugs (pharmacological agents), as opposed to chemicals, you can sometimes get better prices or a larger selection from other vendors. Check out Tocris (http://www.tocris.com, customer # HAR002A), or Calbiochem (http://www.emdbiosciences.com/html/CBC/home.html). These vendors also provide more extensive information about a compound’s biological actions, solubility, storage.
