Source and scale

Without comprehensive supplier information, finding the right chemicals for your projects can be next to impossible. Supplier data is integrated in CAS SciFinder, helping you quickly find and compare commercially available chemical products.

  • Identify suppliers and compare availability and cost.
  • Streamline procurement with direct links to verified vendors.

For commercial users who require a more in-depth, global database of regulatory information in addition to supplier data, learn more about CAS Chemical Compliance Index™.
