Allgemeine Beschreibung

Myristyltrimethylammoniumbromid ist eine kationische/zwitterionische Tensidart. [1]

Anwendung

Myristyltrimethylammonium wurde in einer Studie zur Bewertung einer Tensid-kontrollierten Synthesemethode verwendet, um eine Nanophase einer mesoporösen Ceroxid-Zirkoniumoxid-Festlösung zu erhalten, die kationische Defekte in der Kristallstruktur enthält. [2] Es kam außerdem in einer Studie zur Ermittlung des niedrigen Molekulargewichts organischer Säuren in Böden und Pflanzen durch Kapillarzonenelektrophorese zum Einsatz. [3]

Two fatty acids, perfluorononanoic acid (C(8)F(17)COOH) and nonanoic acid (C(8)H(17)COOH), were mixed with a cationic hydrocarbon surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), in aqueous solutions for comparative investigation. Phase behaviors of the two systems are quite different because of the special properties

Keeping in view the use of surfactants in drug delivery, the interactions of surface active ionic liquids, such as 1-tetradecyl-3-methylimidazolium bromide (C(14)mimBr), with drugs, viz., dopamine hydrochloride (DH) and acetylcholine chloride (AC), have been studied, and the results are further

Fragen

1-2 von 2 Fragen  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 Antwort
    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 Antwort
    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.
