Description générale

Radical initiator

Application

  • Polymer Chemistry: Analysis of polymer synthesis using AIBN under various conditions, with emphasis on thermal initiation properties (Suriyanarayanan & Nicholls, 2019).
  • Influence of cyclodextrin on the UCST-and LCST-behavior of poly (2-methacrylamido-caprolactam)-co-(N, N-dimethylacrylamide): Explores the role of AIBN in copolymerization processes influencing polymer properties relevant to material science applications (Burkhart & Ritter, 2014).
  • Preparation and characterization of polyaniline microcapsule loaded with 2, 2′‐azobis (2‐methylpropionitrile) initiator and its controlled release: Demonstrates innovative applications of AIBN in microencapsulation techniques, targeting enhanced performance in adhesive industries (Zhang et al., 2022).

Highly efficient removal of endocrine-disrupting compounds (EDCs) such as 17beta-estradiol (E2), 4-nonylphenol (NP) and atrazine from water was achieved using a novel macroporous adsorption medium. The medium consisted of a macroporous poly(vinyl alcohol) (PVA) cryogel with molecularly imprinted polymer (MIP)

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
