Requirements for Inclusion of "Order from Source" Links

If you would like your catalog items available as "Order from Source" follow these steps:

  1. Provide links with each substance that will take a CAS SciFindern user directly to the catalog page where they can order your chemicals.
  2. The linking page needs to include current price, current availability, and the ability to directly place an order. Additionally, from your page, CAS SciFindern users should be able to determine how soon the chemical of interest will ship. For instance "ships within 1 week" or "in stock item that ships within 1 week"
  3. Requiring a login to complete the order is acceptable, but having to log in before seeing price and availability, is not acceptable.

The following illustration shows all criteria being met:

Links that do not meet all these requirements may be included as basic "Product Information" links as shown below.
