Opis ogólny

Reacted with dioxaphosphorinanes and iron catalyst to generate rearranged phosphonium ylide products.[1]

Zastosowanie

Diisopropyl azodicarboxylate (DIAD) is a commonly used reagent in organic synthesis for the preparation of useful chemical intermediates. It is often used in the Mitsunobu and aza-Baylis-Hillman reaction.[2][3] DIAD is also used as a selective deprotecting agent of N-benzyl groups.[4]
Reactant for preparation of:
  • Chromenes resembling classical cannabinoids
  • MK-3281 inhibitor of the hepatitis C virus NS5B polymerase
  • Norbornene-based guanidine-rich polymers as mimcs of cell-penetrating peptides (CPP)
  • Analogues of the Pseudomonas aeruginosa quorum-sensing molecule N-(3-Oxododecanoyl)-l-homoserine lactone with immunosuppressive but non-LasR-inducing properties
  • Acceptor-donor-acceptor organic dyes for dye-sensitized solar cells
  • 1,3-dioxane-2-carboxylic acid derivatives as PPARα/γ dual agonists
  • Hydrazinophosphonates and hydrazinobisphosphonates via Mitsunobu and Arbuzov-type multicomponent application of the Morrison-Brunn-Huisgen betaine

Many bio-adhesive materials adhere weakly to tissue due to their high water content and weak structural integrity. Others provide desirable adhesive strength but suffer from rigid structure and lack of elasticity after administration. We have developed two water-free, liquid four-armed

A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphine ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorporate nucleophiles derived from aliphatic alcohols and phenols.

Cancer immunotherapy has been revolutionized by the development of monoclonal antibodies (mAbs) that inhibit interactions between immune checkpoint molecules, such as programmed cell-death 1 (PD-1), and its ligand PD-L1. However, mAb-based drugs have some drawbacks, including poor tumor penetration and

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
