General description

2H-1,2,3-triazole is tautomeric form of 1H-1,2,3-triazole. 1H-1,2,3-triazole effectively promotes the proton conduction in polymer electrolyte membranes via an intermolecular proton-transfer mechanism.[1]

Application

  • Crystalline framework materials: Research on triazole carboxylic acid ligand has demonstrated its application in smart crystalline framework materials, notably for fluorescence sensing and catalytic reduction of p-nitrophenol, illustrating its utility in chemical sensing and environmental applications (Lv et al., 2023).
  • PXR receptor modulation: 1H-1,2,3-Triazole-4-carboxamides have been optimized as potent and selective inverse agonists and antagonists of the PXR receptor, providing insights into the design of receptor-specific drugs (Li et al., 2022).
  • Large-scale synthesis: The large-scale synthesis of a Notum inhibitor employing a modified Sakai reaction illustrates the importance of 1H-1,2,3-triazole in the production of biochemical reagents, which can be essential in medical research and drug development (Atkinson et al., 2022).

Questions

1–2 of 2 Questions  

  1. 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.

  2. 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
