Aplicación

Sodium sulfate can be used as a catalyst:
  • In the Suzuki-Miyaura cross-coupling reactions of aryl halides with arylboronic acids to synthesize biaryl compounds in the presence of PdCl2.
  • For the aminolytic depolymerization of PET (polyethylene terephthalate) bottle waste.
It can also be used as an additive in the Pd-catalyzed Sonogashira reaction of terminal alkynes with aryl halides to synthesize polyfunctional alkynes.

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
