一般說明

聚乙烯吡咯烷酮[聚(N-乙烯-2-吡咯烷酮)，PVP]是一种稳定的、大分子、无毒的非离子型聚合物。广泛应用于医疗、工业、制药、食品、化妆品和电子行业。可通过N-乙烯-2-吡咯烷酮的自由基聚合反应形成。[1][2]

應用

聚乙烯吡咯烷酮(PVP)可作为：
  • 金属纳米颗粒(NP)合成的稳定剂，因为其疏水碳链产生的排斥力可防止纳米粒子团聚。[1][2]
  • 作为杆状羟磷灰石(HAp)纳米粒子合成中的封端剂，控制羟磷灰石晶体的成核和生长。[3]
  • 在制药行业中用作药物分散和悬浮的合成聚合物溶媒。[4]
  • 溶液聚合的乳化剂和崩解剂[5]

其他說明

聚乙烯吡咯烷酮是 Denhardt′s 溶液的一种成分，在标准 50X 储备溶液中的浓度为 1%（w/v）。

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.
      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
