一般說明

[2-(甲基丙烯酰基氧基)乙基]二甲基-(3-磺酸丙基）氢氧化铵（DMAPS）是一种用于合成聚磺基甜菜碱的吸湿性两性离子单体。聚磺基甜菜碱是电中性聚合物，其一个单体单元内含有阳离子和阴离子两种基团，并且具有有趣的性质，例如在盐水溶液中的抗电解质行为、生物相容性和血液相容性。这些性质使聚磺基甜菜碱可用于许多生物医学应用，如药物递送和药物制剂。

應用

由于[2-(甲基丙烯酰基氧基)乙基]二甲基-(3-磺酸丙基）氢氧化铵（DMAPS）具有吸湿性，其每个单体单元含有最多一分子的水。该材料应储存在阴凉干燥处，并且有些反应条件可能需要在聚合前除去水。

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. Does this product contain any inhibitor (e.g., MEHQ, BHT) to increase shelf life? Thank you.

    1 answer

    1. An inhibitor is not included in this product. Typically, inhibitors are added to compounds that are in liquid form at room temperature. This material is a crystalline powder.
