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

  5. How should I store ChemDose® tablets?

    1 answer

    1. 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.
