일반 설명

Iodine exhibits exceptionally high dielectric polarization in various solvents (dioxane, isobutylene, p-xylene and benzene).[1]

애플리케이션

Catalyst for synthesis of esters by condensation of carboxylic acids with alcohols or transfesterification.

A mild and efficient method for esterification and transesterification catalyzed by iodine
Iodine has been used for the easy visualization of 9-bromononanoic acid, allyl ester by thin layer chromatography (TLC).[2] It has also been used for the preparation of oxidation solution, required for the synthesis of oligodeoxynucleotides bearing 3′-terminal phosphorothioate.[3]
Iodine may be used to catalyze:
  • Synthesis of 5-(4-nitrophenyl)-10,15,20-triphenylporphyrin.[4]
  • Oxidative C-H bond amination of saturated hydrocarbons.[5]
  • Protection of amines with benzyloxycarbonyl (Cbz) group.[6]
  • Direct oxidative coupling/annulation of β-keto esters or 2-pyridinyl-β-esters with alkenes to form dihydrofurans and indolizine, respectively.[7]
  • Thiocyanation of aromatic systems to form aryl thiocyanates.[8]
  • Esterification of cellulose with acetic anhydride to form cellulose triacetate.[9]

질문

1–3 / 3 질문  
  1. Can I dilute the powder in ddH2O and store it as such?

    1 답변
    1. The solubility and solution stability are not determined for this product. In general, iodine solutions can be stored at room temperature; however, a literature search is recommended for additional stability considerations.

      도움이 되었습니까?

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 답변
    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.

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변
    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
