Allgemeine Beschreibung

Iodine monochloride is an interhalogen compound.[1] It forms various complexes with ethyl, isopropyl and t-butylbenzenes.[2] Electrically conducting solution of ICl is obtained on dissolution of ICl in polar solvents.[3] ICl is a green oxidizing agent and participates in the following transformations:[4]
  • aldose hemiacetals to the corresponding aldose lactones
  • diarylmethanols to the corresponding diarylmethanones
  • arylalkylmethanols to the corresponding arylalkylmethanones
  • dialkylmethanols to the corresponding dialkylmethanones

Anwendung

Iodine monochloride (ICl) may be employed as a reagent in the following processes:
  • Halogenation of methoxy and dimethoxybenzenes[3]
  • Synthesis of flavones.[5]
  • Preparation of 1-naphthaldehydes.[1]
It may be used as an iodinating agent in the conversion of alkylboranes to alkyl iodides.[6]

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
