General description

[2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS) is a hygroscopic, zwitterionic monomer used in the synthesis of polysulfobetaines. Polysulfobetaines are electrically neutral polymers that contain both cationic and anionic groups within a single monomer unit and feature interesting properties such as antielectrolyte behavior in aqueous salt solutions, biocompatibility, and hemocompatibility. Based upon these properties, polysulfobetaines are useful in many biomedical applications such as drug delivery and drug formulation.

Application

Due to its hygroscopic nature, [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS) can contain up to one molecule of water per monomer unit. This material should be stored in a cool, dry place and depending on the reaction conditions, water may need to be removed prior to polymerization.

Questions

1–3 of 3 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

  3. Does this product contain any inhibitor (e.g., MEHQ, BHT) to increase shelf life? Thank you.

    1 answer

    1. An inhibitor is not included in this product. Typically, inhibitors are added to compounds that are in liquid form at room temperature. This material is a crystalline powder.
