Sourcing database: Available Chemicals Directory (ACD)

Why should we license ACD, if there are numerous free-of-charge offers on the Internet to search for suppliers?
  1. There are also numerous suppliers for each compound. ACD helps you to select the best supplier
    • collecting all supplier information under one structure record
    • providing prices
    • sort by normalized prices
    • set your preferred supplier
    • add files with your own company prices
  2. Knowing where to buy a compound is only a small part of the whole ordering process. Out of the box ACD has already a shopping cart. If you want a complete solution, please ask for LOGISTICS.
  3. Integrates with other databases, such as reaction databases. An icon under a structure automatically tells you if the compound is available.
  4. ACD can be incorporated as in-house database or as web service into your own application.
  5. Export answer list into SDFiles or Excel.
