Application


  • Environmental Sensing: Diethanolamine was used in the development of a colorimetric sensor array for detecting and discriminating various analytes, showcasing its application in environmental monitoring and safety (Adampourezare et al., 2024).

  • Shrimp Metabolism Research: The compound was part of a study exploring the impact of rearing environments on shrimp metabolism, helping to trace the origins and species of shrimps using specific metabolites, thus enhancing the understanding of aquatic life in food science (Ao et al., 2024).

  • Novel Electrochemiluminescence Probes: Diethanolamine facilitated the creation of highly active coreactant-capped, water-stable 3D@2D core-shell perovskite quantum dots, serving as a powerful self-enhanced electrochemiluminescence probe for analytical chemistry applications (Sun et al., 2024).
