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.

Descripción general
Aplicación
- As a cationic monomer to synthesize polyampholyte hydrogels (PAHs). These hydrogels show pH-responsive and ionic strength-responsive behavior and are suitable for application in smart coatings and biosensors.
- As a monomer to prepare poly(APTAC) ion exchange membranes with high surface porosity, for the removal of Cu(II), Cr(VI), and As(V) ions from water.[1]
- As a precursor to fabricate cartilage mimetic polymer scaffolds that can be used in cartilage regeneration and replacement.[2]

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Why is this sold as a 50% wt soln in water? Is it stable as a solid?
1 answer-
The compound (3-Acrylamidopropyl)trimethylammonium chloride is generally sold in solution, i.e. in a liquid form vs a dry form, to facilitate the addition of a stabilizer against premature polymerization. For this product, it is 3,000 ppm monomethyl ether hydroquinone that is used as a stabilizer.
