一般描述

丁二酸酐是丁二酸的五元环环酸酐。它被广泛应用于高分子材料、医药、农用化学品、染料、表面活性剂、有机阻燃材料的制造。它也可作为离子交换膜的交联剂和环氧树脂的固化剂。

应用

琥珀酸酐可用于制备：
  • 共价交联的氧化藻酸盐/N-琥珀酰-壳聚糖水凝胶，作为组织工程的注射系统。[1]
  • 制备芯片上的功能化氧化物表面。[2]
  • 作为起始原料，以金属三氟酸盐作为催化剂合成聚酯。
  • 作为交联剂提高玉米蛋白膜的力学性能和抗菌活性。

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.
