Descripción general

El cloruro de glicidiltrimetilamonio (GTMAC) es un agente cationizante utilizado habitualmente para la modificación del almidón.[1]

Aplicación

El cloruro de glicidiltrimetilamonio se ha utilizado como agente derivatizante para sintetizar cloruro de N-(2-hidroxipropil)-3-trimetilamonio quitosano (HTCC), un derivado quitosano hidrosoluble, por reacción con el quitosano. El HTCC puede formar películas de nanocompuestos con nanopartículas de plata que muestran buenas propiedades antimicrobianas y transparencia óptica.[2] También pueden prepararse almidones catiónicos por derivatización del almidón con GTMAC.[3]

Precaución

hidrólisis durante el almacenamiento (aprox. 3,5 %/mes a 20°C)

Soft cationic core/shell cellulose nanospheres can deform and interpenetrate allowing their self-assembly into densely packed colloidal nanogel layers. Taking advantage of their water-swelling capacity and molecular accessibility, the nanogels are proposed as a new and promising type of coating material

An efficient and effective process for the production of high-performance anion exchange membranes (AEMs) is necessary for the commercial application of fuel cells. Therefore, in this study, quaternized poly vinylbenzyl chloride (QVBC) and polysulfone were composited with glycidyltrimethylammonium-chloride-quaternized chitosan (QCS)

Questions

1–4 of 4 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. From this information “Caution hydrolysis on storage (approx. 3.5%/month at 20°C)”  If I keep in storage -18 °C it’s can keep product from approx.? Or reduce some loss?

    1 answer

    1. The recommended storage temperature for the product is 2-8 °C. The retest period for this item is approximately one year from the quality release date when stored in these conditions. There is no stability information available regarding storage at -18°C.
