General description

Boron tribromide is a strong Lewis acid generally employed in the deprotection of -OH and -NH groups. It is a moisture-sensitive liquid, which is also used to cleave esters or ethers into alkyl bromides.

Application

Reactant for preparation of:
  • Drug intermediate 6-nitro-L-DOPA
  • Luminescent polystyrene derivatives with sterically protected carbazolylborane moieties
  • High-quality boron-doped graphene via Wurtz-type reductive coupling reaction
  • Mercapto-(+)-methamphetamine haptens for synthesis of (+)-methamphetamine conjugate vaccines with improved epitope densities
  • Micrometer-sized organic molecule-DNA hybrid structures
  • Borane complexes via electrophilic aromatic borylation reactions
  • A 5-HT2C receptor agonist
  • Biphenyl-derivatives possessing tertiary amino groups as β-secretase(BACE1) inhibitors for the treatment of Alzheimer′s disease
  • A highly near-IR region fluorescent p-extended boron aza-dipyrromethene moiety unit
  • Tetrahydroisoquinoline derivatives via intramolecular cyclization of methoxy-substituted N-phenethylimides
Used to cleave aryl methyl ethers in a synthesis of a benzopyranobenzopyran from a coumarin scaffold.

Questions

1–3 of 3 Questions  
  1. 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/418/501/product-dating-information-06-25-mk.pdf

  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
