Application

Reagent for the preparation of Boc protected amines.
Aminomethyl allene was prepared by reaction of Boc propargyl amine with formaldehyde, diisopropylamine and copper bromide as part of a series of Bovine Plasma Amine Oxidase inactivators.
Tris-Boc protected hydrazine allows preparation of Fmoc ester in a chromophoric reagent to monitor solid-phase aldehydes.

Automated Boc protection and deprotection can be done using Synple Automated Synthesis Platform (SYNPLE-SC002), Boc protection cartridges ((SYNPLE-B001), (SYNPLE-B002), and Boc deprotection cartridges (SYNPLE-B011)
Reagent for the introduction of the Boc protecting group.
Protection of alcohols as Boc derivatives via Lewis acid catalysis.

Questions

1–2 of 2 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
