Aplicación

Borane pyridine complex is commonly used as a reducing reagent for the reductive amination of aldehydes and ketones.[1] It is the precursor to synthesize carbon-based material, BC4N.[2] Along with iodine, it can be used as a reagent for hydroboration of alkenes and alkynes.[3]
Used for:
  • Investigations of site energy distribution functions from Toth isotherm for adsorption of gases on heterogeneous surfaces
  • Preparation of α−alkyl-β-hydroxy esters
  • Regioselective immobilization of short oligonucleotides to acrylic copolymer gels
  • Preparation of Igs conjugated with viral peptide epitopes
  • Sintering of silicon carbide

In this note, we describe a method devised to detect, by means of mass spectrometry (MS), tryptophan-containing peptides and proteins using pyridine-borane. This reagent selectively reduces tryptophan residues, converting them to 2,3-dihydro-tryptophan, thereby enabling quantitation of tryptophans.

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
