일반 설명

Benzhydroxamic acid (BHA) reacts with BiPh3 or Bi(O(t)Bu)3 to afford novel mono- and di-anionic hydroxamato complexes, having anti-bacterial activity against Helicobacter pylori.[1] Three-dimensional structure of recombinant horseradish peroxidase-BHA complex has been studied.[2]

애플리케이션

Benzhydroxamic acid may be employed for the Pd-catalyzed synthesis of benzisoxazolones.[3]

An external-oxidant-free process to access the isoquinolone motif via cross-coupling/cyclization of benzhydroxamic acid with alkynes is described. The reaction features a regioselective cleavage of a C-H bond on the benzhydroxamic acid coupling partner as well as a regioselective alkyne insertion.

질문

1–2 / 2 질문  

  1. 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

  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.
      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
