General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Catalyst for:
  • Stille reaction
  • Hydrogenation reactions
  • Suzuki-Miyaura cross-coupling and Heck-Mizoroki reactions
  • Deoxygenation
  • Oxidation reactions
  • Coupling reactions
Palladium on carbon (Pd/C) (10 wt. % loading, matrix activated carbon support) can be used as a catalyst in the well known reactions like hydrogenation of alkenes, alkynes, ketones, nitriles, imines, azides, nitro groups, benzenoid and heterocyclic aromatics; hydrogenolysis of cyclopropanes, benzyl derivatives, epoxides, hydrazines, and halides; dehydrogenate aromatics and deformylate aldehydes.
It can also be used as:

  • A catalyst for hydrodechlorination of dichlorodifluoromethane (CCl2F2), which is a known greenhouse gas[1],
  • A catalyst for Heck reactions of aryl halides in ionic liquids[2]
  • An anode catalyst for the fabrication of direct formic acid fuel cells (DFAFC)[3]
  • A cost-effective electrocatalyst for the oxidation of methanol[4]
  • In the catalytic hydrogenation of chemical hydrides for the production of hydrogen[5]
  • A catalyst in Suzuki-Mayaura reaction[6]
Product can be used with our benchtop hydrogen generator, H-Genie Lite (Z744083)

Questions

1–10 of 11 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. 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
