一般說明

N-叔-丁基二甲基甲硅烷基-N-甲基三氟乙酰胺是一种高反应性的硅化试剂,常用于对羧酸、醇、胺和巯基进行硅化反应。它还被用作保护试剂和去保护试剂。 [1]

應用

N--丁基二甲基甲硅烷基-N-甲基三氟乙酰胺(MTBSTFA)可:
  • 作为氢氧化芴GC-MS分析中以及氨基酸的GC分析中的衍生化剂。[2]
  • 作为有效甲硅烷基化剂,用于各种不同醇、硫醇、酚、羧酸、胺和酰胺。
  • 用于官能化带极性基团的多壁碳纳米管(MWCNT)。[3][4][5]
据报道,与其他用于GLC衍生化的甲硅烷基化试剂相比,MTBSTFA对水分的敏感性要低得多。

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/449/386/product-dating-information-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
