Descrizione generale

4-Vinylpyridine is a highly reactive alkene monomer due to the presence of a vinyl group and a heteroaromatic ring. It is widely used as a monomer to produce a variety of polymers and copolymers, which are used in various applications including, contact lenses, nanoelectronics, sensors, optoelectronic devices, smart coatings, drug delivery systems, sensors, gas separation, air filtration, and purification processes.

Applicazioni

4-Vinylpyridine can be used as a monomer:
  • In the synthesis or modification of polymers for drug-releasing contact lenses.
  • In the preparation of the zwitterionic polymer, namely poly(4-vinylpyridine propylsulfobetaine). The zwitterionic polymer is utilized for its superior bioinert capability in withstanding clinical sterilization processes, making it suitable for extended medical applications which include the development of biocompatible implants and as a coating material for medical devices.
  • To synthesize the temperature and pH-sensitive copolymer, specifically (N-vinylcaprolactam-co-4-vinylpyridine), which is used in drug delivery systems under certain environmental conditions.
  • The highly charged p(4-vinylpyridine-co-vinylimidazole) particles, which find applications in various fields such as biomedical, catalysis, and environmental applications.
4-Vinylpyridine also plays a role as a functional monomer in the molecular imprinting of the soft contact lens material. Its inclusion, along with other monomers, enhances the affinity of the hydrogel towards brimonidine, resulting in improved binding properties, loading capacity, and controlled release characteristics.

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.
      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
