一般描述

2,6-二-叔t-丁基-4-甲基吡啶是一种位阻型非亲和碱，可区分布仑斯惕（质子）酸与路易斯酸。它也可直接将乙醛[1]和酮[1][2]高产率转化成乙烯基三氟甲磺酸酯。它可抑制GaCl3-催化苯酚邻乙基化[3]反应中产物的脱硅和水合作用。

应用

2,6-二- 叔 -丁基-4-甲基吡啶用于：
  • 1,2-二氢-2-硅杂萘衍生物的合成[4]
  • 高炔丙基叠氮衍生物在 PtCl 4 催化下的环化反应[5]
  • β-硫代吡喃核苷的非对映选择性合成[6]

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.
