General description

4-(Dimethylamino)pyridine (DMAP) is a highly versatile nucleophilic catalyst for acylation reactions and esterifications. It is also employed in various organic transformations like Baylis-Hillman reaction, Dakin-West reaction, protection of amines, C-acylations, silylations, applications in natural products chemistry, and many others.

Application

4-(Dimethylamino)pyridine can be used as a catalyst:
  • To synthesize 3,5-disubstituted 2,6-dicyanoaniline by reacting malononitrile, aldehydes, and β-nitroolefins.
  • For the acylation of alcohols with acid anhydrides under auxiliary base- and solvent-free conditions to synthesize corresponding esters.
  • In Baylis-Hillman reaction to form carbon-carbon bond by the coupling of an activated alkene with an aldehyde or ketone.
A highly efficient catalyst for acylation reactions

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.

  2. 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
