Aplicação

Dimethyl phosphite is used in the synthesis of α-aminophosphonates, which are medicinally important phosphorus analogs of amino acids, by treating with an amine and an aldehyde or a ketone.[1][2] It can also be employed in asymmetric hydrophosphonylation of aldehydes to synthesize optically active α-hydroxy phosphonates.[3]
Dimethyl phosphite may be used as an effective alternative to organic tin hydrides as radical reducing agents for organic halides, thionoesters, and isocyanides to form the corresponding hydrocarbons.[4] Radical translocation/cyclization reactions of terminal alkynes to form cyclic phosphonates can also be effectively carried using dimethyl phosphite as a reagent under tin-free condition.[5]

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
