Certificate of Analysis

Certificate of Origin

  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. How should I dispose of spent ChemDose® tablets?

    They should be treated as solid waste, contaminated with reaction species. The matrix is non-toxic and environmentally benign.

  4. How should I store ChemDose® tablets?

    As with most catalysts and ligands, as a general precaution it is best to store them in a refrigerator and/or under an inert atmosphere to maintain activity. Some catalysts, such as Pd(dppf)Cl2·CH2Cl2, are more robust and can be handled in air without issue. Please refer to the ChemDose® label for specific handling of a given catalyst, ligand, or reagent.

  5. Can I use ChemDose® tablets in any solvent?

    Yes, including aqueous solvents.

  6. Do the ChemDose® tablets disintegrate during the course of the reaction?

    They are normally recovered intact, however, they may disintegrate somewhat in aqueous reactions. Any disintegrated tablets can be removed from the reaction via filtration.

  7. What is the pH stability of the ChemDose® tablets?

    The ChemDose® tablets are mildly basic and will dissolve in the presence of mineral acids. 

  8. Can I use ChemDose® tablets in a microwave or pressure vessel?

    Absolutely. Please see the Technical Information for Download section (below) for additional examples of cross-coupling reactions involving the use of microwaves.

The total synthesis and structural confirmation of naturally occurring all l-cyclic tetrapeptide pseudoxylallemycin A is reported. X-ray crystallography revealed that the linear precursor adopted an all-trans (ttt) extended linear conformation, while its cyclic derivative adopts a trans,cis,trans,cis (tctc) conformation. Two...
