General description

Diallyldimethylammonium chloride (DADMAC) is a quaternary ammonium compound available in solid form with an assay of ≥97.0%. It serves as a versatile monomer in various polymerization processes and is primarily used in the production of cationic polymers. These polymers are essential in a range of applications, particularly in the fields of water treatment, paper production, and personal care products. Additionally, DADMAC exhibits antifouling properties, making it valuable for applications where the prevention of biofilm formation and surface fouling is critical.[1][2][3]

Application

Diallyldimethylammonium chloride can be used as:
  • A precursor for the synthesis of poly(diallyldimethylammonium chloride) (PDADMAC), which is widely used in various applications related to water purification and wastewater management.
  • a monomer in the synthesis of cationic hydrogels via radical polymerization. The resulting polymer, poly(diallyldimethylammonium chloride) (PDADMAC), features a high cationic charge density, which is crucial for effectively binding anionic dyes. This property makes PDADMAC-based hydrogels valuable materials for wastewater treatment applications.
  • DADMAC has been used in dental biomaterials to enhance their antifouling properties. When incorporated into acrylic resins, it provides effective antibacterial and antifungal activity without compromising biocompatibility

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.
