General description

Chemical structure: imidazole

Application

Thiabendazole (TBZ) is a broad-spectrum antihelminthic and is used to treat parasitic infections in humans. It is used as an agricultural fungicide and as a food preservative[1]. Thiabendazole has been used as a heavy metal chelating detoxification agent. It is used clinically to treat threadworm, cutaneous larva migrans, visceral larva migrans, and trichinosis[2].

Biochem/physiol Actions

Thiabendazole inhibits anaerobic respiration at the level of mitochondrial helminth-specific enzyme. It acts as a quinol-fumarate reductase (QFR) inhibitor in ,C. jejuni and H. pylori, blocking quinol oxidation to quinone. Thiabendazole suppresses egg and larval production and may inhibit the subsequent development of eggs and larvae which are passed in feces[2]. A proposed route of biotransformation of thiabendazole is the CYP1A2-catalyzed hydroxylation to 5-hydroxythiabendazole, which is metabolized to glucuronide and sulfate conjugates[1].

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
