一般描述

4-氨基苯甲酸 (4-ABA) 作为细菌辅助因子，参与叶酸的合成。[1]它是一种通过线性氢键结合进行结构扩展的通用试剂，涉及羧酸和胺官能团。[1]用氨基阳离子自由基法在玻碳电极 (GCE) 上制备了 4-ABA 单层膜。[2]合成了 4-ABA 的分子加合物，用红外光谱和 X-射线衍射方法对其进行了表征。[3]

应用

4-氨基苯甲酸可用于下列研究：
  • 玻碳电极的共价修饰。[4]
  • 1，4-（2-氯亚苯基）氨基苯甲酸（席夫碱）的合成。[5]
  • 分光光度法测定微量多巴胺、甲基多巴和左旋多巴。[6]
  • 5-磺基水杨酸与 1：1 质子转移化合物的合成。[1]

Questions

1–3 of 3 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

  3. Hallo, wie lange ist die Haltbarkeit des Produkts? auf dem Gebinde und dem Zertifikat gibt es dazu keine Angaben.

    1 answer

    1. This product is not assigned an expiration date or recommended retest date. Customers should routinely inspect products with no expiration date or recommended retest date to ensure they perform as expected. These products are also subject to a one-year warranty from the date of shipment.
