Descrizione generale

Isopropylmagnesium chloride is a highly reactive organomagnesium halide formed by the reaction of magnesium metal with isopropyl chloride. It is used in the Grignard reaction to form new carbon-carbon bonds.

Applicazioni

Isopropylmagnesium chloride solution (2.0 M in THF) can be used as a reagent to synthesize:      
  • 2,6-Diiodobenzaldehyde derivatives via regioselective metal-iodine exchange of 5-substituted 1,2,3-triiodobenzene in the presence of ethyl formate as a formylating agent.      
  • Arene and heteroarene sulfonamides from aryl and heteroaryl bromides via the formation of corresponding Grignard reagents.
  • Symmetrical pyridyl monoselenides by treating with bromo/iodopyridines followed by quenching with selenyl chloride, SeCl2.

Confezionamento

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

Substantial progress has been made in magnesium–halogen exchange reactions used for the preparation of functionalized Grignard reagents containing sensitive moieties such as ester or cyano groups.

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.
