Opis ogólny

o-Toluenesulfonamide is a major impurity in artificial sweetening substances containing saccharin[1]. Determination of o-toluenesulfonamide in saccharin and saccharin sodium by reversed-phase HPLC method has been reported[2].

Zastosowanie

  • Dynamic ligand reactivity in a rhodium pincer complex.: Discusses the role of o-toluenesulfonamide as a ligand in advanced chemical syntheses, demonstrating its utility in creating reactive intermediates for catalytic processes (Tang et al., 2015).
  • Reaction of arylium ions with the collision gas N2 in electrospray ionization mass spectrometry.: Highlights the use of o-toluenesulfonamide in mass spectrometry studies to understand ionization mechanisms, aiding in the identification of complex chemical structures (Liang et al., 2015).
  • Benzosulfonamides in wastewater: method development, occurrence and removal efficiencies.: Focuses on the development of methods to detect and remove o-toluenesulfonamide from wastewater, emphasizing its prevalence and the challenges associated with its elimination (Ajibola et al., 2015).

A gas-liquid chromatographic (GLC) procedure with p-toluenesulfonamide (p-TS) as an internal standard is used to determine o-toluenesulfonamide (o-TS), a major impurity in artificial sweetening substances containing saccharin. Although p-TS can itself occur as an impurity in samples, it is usually

Questions

1–2 of 2 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
