一般描述

联苯-4,4′-二甲酸(BPDC)属于单体类,称为芳香族二羧酸。它用于制备基于BPDC的聚合物,这些聚合物表现出优异的热稳定性,适用于需要高温抗性的应用。这些聚合物还因其低介电常数和高击穿强度而显示出高电气绝缘性能。它们在电气和电子工业中可用于高性能电子设备的绝缘、封装和制造。[1]

应用

联苯-4,4′-二羧酸可用于:
  • 在芳香族聚酯的合成中作为关键组分,这些聚酯对于液晶聚合物的开发极具价值,在电子、光学设备、汽车和纺织领域具有潜在应用。
  • 作为金属-有机框架(MOF)合成中的连接剂或配体,在气体储存、催化、传感和分离技术等领域具有广泛的潜在应用。
  • 在生物医学应用中,作为合成具有生物活性的各种药物化合物和材料的构建块。由于其化学性质,它还可用于开发药物输送系统和生物材料。

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.

  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
