General description

N-(Hydroxymethyl)acrylamide (NHMA) is a bifunctional monomer with both a reactive vinyl group and a hydroxymethyl group, making it significant in polymer chemistry. It is known for forming hydrophilic, cross-linked networks, with applications in biomedical fields such as drug delivery systems, contact lenses, and tissue engineering, as well as in industrial UV-curable resins. NHMA is commonly used in hydrogel formulations for drug delivery and wound dressings. Additionally, it can be applied in creating bioadhesives or sealants for medical purposes, such as sealing wounds or attaching medical devices to tissues.

Application

N-(Hydroxymethyl)acrylamide can be used as:
  • A monomer in the development of polymer gel dosimeters specifically designed for radiation therapy applications. The incorporation of NHMA enhances the sensitivity of the dosimeter to radiation doses.
  • A monomer in the development of thermo-responsive polymeric gates, which exhibits thermo-responsive behavior. The incorporation of NHMA enhances the overall properties of the polymer, allowing for better control over the release mechanisms in response to temperature changes.
  • A key monomer in the synthesis of double-hydrophilic and amphiphilic block glycopolymers, contributing to their self-assembly properties, biocompatibility, and functionalization potential. These characteristics make NHMA-based glycopolymers valuable for various biomedical applications, including drug delivery systems, biosensors, and tissue engineering.

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/418/501/product-dating-information-06-25-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
