  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Where can I find more information on the possible applications of Product 669032, PEPPSI-IPr catalyst?

    ChemFiles 6.3 explores the advantages and reaction applications of the PEPPSI-IprTM catalyst.

  4. When using Product 669032, PEPPSI-IPr catalyst, how can I remove any trace palladium from the reaction mixture after the reaction is complete?

    You may be interested in the QuadraPure metal scavengers, like Product No. 665422. These functionalized beads can effectively remove selected trace metallic impurities in a relatively easy process.

  5. What is the difference between Product 669032, PEPPSI-IPr catalyst, and the ChemDose version, Product 685143?

    Both products are the same catalyst, but in different forms. Product 669032 is a powder, while 685143 is the catalyst in tablet form. A specific amount of catalyst (2μmol for 685143) is impregnated into an inert tablet matrix as a time-saving alternative to weighing out the catalyst. More information on the ChemDose tablets is found at:
