一般描述

Cyanogen bromide (CNBr) is a halogen halide. Its utility as a condensing agent during chemical ligation of oligodeoxyribonucleotides has been reported.[1] Its threshold photoelectron (TPE) spectrum has been recorded under high resolution.[2] The cryopolymerization of CNBr on irradiation has been investigated.[3]

应用

用于肽的断裂[4]和用于蛋白质固化过程。[5]与 C60Ph5Cl 反应生成新型苯代异喹啉并[3′,4′:1,2][60]富勒烯。[6]
Cyanogen bromide may be used:
  • To activate polysaccharides for coupling with erythrocytes.[7]
  • As an oxidizing agent in urine thaimine assay.[8]
  • In the preparation of 2-amino-5-(2′-thienyl)-1,3,4-oxadiazole.[9]

Questions

1–3 of 3 Questions  
  1. Hi, is this sterile and suitable for cell culture? Thank you.

    1 answer
    1. This product is not sterile and has not been tested for cell culture applications. Therefore, it may not be suitable for use in cell culture without proper sterilization procedures.

  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

  3. 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.
