Opis ogólny

2-Methylpyridine borane complex is a nontoxic alternate to the reducing agent sodium cyanoborohydride.[1]

Zastosowanie

2-Methylpyridine borane complex solution (2-Picoline borane complex) was used as reducing agent for the labeling of oligosaccharides by reductive amination.[2] It may be used in the following studies:
  • Synthesis of alkoxyamine derivatives, via reduction of oxime ethers.[3]
  • Reductive amination reactions of C1-C10 aldehyde 2,4-dinitrophenylhydrazones.[4]
  • Synthesis of various trifluoromethylated amino compounds.[5]
  • An alternative reagent for reductive aminations.[6]
Environmentally benign reducing agent

Reactant for:
Reductive amination
N-Benzyl-protection of amino acid derivatives by reductive alkylation
Reductive alkoxyamination

A new method for the determination of carbonyls in air using 2,4-dinitrophenylhydrazine (DNPH) has been developed. The traditional method for the measurement of carbonyl compounds, using DNPH to form the corresponding 2,4-dinitrophenylhydrazone (DNPhydrazone) derivatives, is subject to analytical errors because

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.
