Allgemeine Beschreibung

Bromobenzene is an aryl chloride. It participates in the optimized palladium/metal oxide systems catalyzed Heck reactions of the non-activated and deactivated aryl chlorides.[1] Heck reaction of bromobenzene with styrene using palladacycle as catalyst has been reported.[2] It induces hepatic necrosis, via the formation of a reactive metabolite.[3]

Anwendung

Bromobenzene can be used as a reactant for the cross-coupling reactions such as Suzuki coupling reaction to synthesize a variety of unsymmetrical biaryls[4] and Mizoroki−Heck reaction to synthesize various substituted alkenes.[5][6] It is also an effective quencher for the fluorescence quenching of anthracene.[7][8]
Bromobenzene was used in the synthesis of four-armed star chain transfer agent, required for the preparation of amphiphilic star graft copolymers.[9] It was employed as organic extraction phase in the Ion pair-based dispersive liquid-liquid microextraction of ultratrace levels of gold in water samples, soils and river sediments.[10]

Fragen

1-2 von 2 Fragen  

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

    1 Antwort

    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

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

    1 Antwort

    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
