一般說明

4-氯-7-硝基苯并呋喃(NBD-Cl)是一种高度灵敏的发色和荧光试剂。[1]据报道,它能与 -1-甲氧基-3-(三甲基硅氧基)-1,3-丁二烯(Danishefsky二烯)发生自发反应,通过正常电子需求的Diels-Alder(NEDDA)反应,区域选择性地生成烯醇硅醚。[1]已有研究对NBD-Cl进行了分子结构、振动光谱和NBO(自然键轨道)分析。[2]它作为柱前衍生剂的用途已被研究。[3][4]

應用

4-氯-7-硝基苯并呋喃(NBD-氯化物)被用于以下研究:
  • 合成荧光磷脂衍生物,即NBD-二癸酰基磷脂酰乙醇胺[5]
  • 合成官能化羟基萘并呋咱。[6]
  • 药物配方中富马酸氯马斯汀、氯雷他定、氯沙坦钾和雷米普利的分光光度法和荧光分光光度法测定。[1]
  • 通过Diels-Alder反应合成7-硝基苯并呋喃(NBD)-标记的马来酰亚胺。[7]

The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. Since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as a "cycloaddition".

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.
      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
