一般描述

4-氨基苯基二硫化物在化学合成中主要用作试剂。它具有硫-二硫交换性质,使其在氧化还原反应和聚合物合成中很有用。它可以参与硫-二硫交换反应,促进与其他硫醇或二硫形成共价键。4-氨基苯基二硫化物通常用作交联剂,特别是在聚合反应中,它可以增强聚合物的机械和热性能。它还可以作为导电聚合物中的掺杂剂或电荷转移剂,提高其导电性。

应用

4-氨基苯基二硫化物可用作:
  • 交联剂在自愈聚脲-氨基甲酸乙酯弹性体合成中的应用。这些自我修复材料在药物输送、伤口愈合、组织工程、电子、航空航天和涂料等各个领域都有应用。
  • 由于存在动态二硫键,使环氧网络能够进行化学回收,因此在可再加工、可修复和可回收的环氧网络配方中的硬化剂。这些环氧网络广泛应用于各种应用,包括复合材料,涂料,粘合剂和纤维增强热固性复合材料。
  • 作为一种交联剂,用于开发环氧树脂和碳纤维复合材料,具有增强的机械性能和多形状记忆能力,在高性能材料中具有潜在的应用前景。
4-氨基苯基二硫醚还可用于以下用途:
生物结合:胺基可以与羧酸或其衍生物反应,使其可用于结合生物分子,如蛋白质和肽。这对于开发靶向药物递送系统尤其有价值,在这种系统中,药物直接与一种可以靶向癌细胞或其他疾病部位的分子相连。
诊断制剂:它可以用来修饰诊断设备的表面,如生物传感器。它们可以帮助将生物分子固定在传感器表面,提高检测的灵敏度和特异性。

It has been shown that certain dogs have erythrocytes characterized by an inherited high concentration of reduced glutathione (GSH), five to seven times the normal level (high-GSH RBCs). We examined whether increased GSH in dog erythrocytes leads to increased protection

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.
