Allgemeine Beschreibung

Dansyl chloride is a fluorogenic reagent which is typically employed for the derivatization of amino acids.[1]

Anwendung

Ein fluorogenes Reagens für die N-terminale Derivatisierung von Aminosäuren und Peptiden und die Detektion durch Umkehrphasen-HPLC.
Dansyl chloride has been used for the fluorogenic labeling of xenoestrogens, 4-nonylphenol and bisphenol A prior to their determination by high-performance liquid chromatography (HPLC) with fluorescence detection.[2] It has also been used for the derivatization of icariin in human serum samples after oral administration of Epimedium decoction, followed by its determination using ultrasensitive LC-tandem mass spectrometry (LC-MS)[3] and for the derivatization of antitumoral agent ES-285 in dog plasma followed by its analysis by HPLC equipped with ultraviolet and fluorescence detection.[1]

Liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) is one of the most prominent analytical techniques owing to its inherent selectivity and sensitivity. In LC/ESI-MS/MS, chemical derivatization is often used to enhance the detection sensitivity. Derivatization improves the chromatographic separation, and

  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.
