Opis ogólny

The product is silica gel functionalized with amino groups. The product (3-Aminopropyl-functionalized silica gel) is 9% functionalized and has 1mmol/g of NH2 loading (extent of labelling). It participates as catalyst in the Knoevenagel condensation reactions.[1]

Zastosowanie

3-Aminopropyl-functionalized silica gel may be used in the following studies:
  • For the separation of polychlorinated biphenyls (PCBs) from lipids by combined supercritical fluid extraction and separation.[2]
  • Preparation of the tin complex immobilized on silica gel, a novel, green, highly efficient and heterogeneous reusable catalyst.[3]
  • Preparation of silica gel bearing isonicotinamide groups.[4]
  • Synthesis of a novel catalytic system including Pd(OAc)2 attached to a bis(oxazoline) ligand that is covalently bonded to 3-mercaptopropyl-functionalized silica gel.[5]
  • Useful as a heterogeneous, reusable catalyst for the Knoevenagel condensation.
  • For low- and medium-pressure reversed-phase liquid chromatography.

Questions

1–2 of 2 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.
