  3. How should I dispose of spent ChemDose® tablets?

    1 answer

    1. 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?

    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.

  5. How does the storage temperature relate to shipping conditions?

    1 answer

    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
