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.

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).
