Beschreibung

Anwendung

• Chemiresistive Sensor Development: Diethylamine was used to enhance the sensitivity of a chemiresistive sensor for CO₂ gas monitoring, demonstrating its utility in environmental and industrial applications (Rath et al., 2024).


• Supercritical Fluid Chromatography: Aromatic stationary phases were synthesized using diethylamine, evaluated based on the linear solvation energy relationship model, which expanded its application in supercritical fluid chromatography (Ge et al., 2024).


• Nanoparticle Synthesis: Diethylamine facilitated the sol-gel method modifications for synthesizing silver-silica nanoparticles, enhancing their theranostic potential in cancer treatment (Nikolopoulou et al., 2023).


• Pharmaceutical Analysis: Diethylamine was key in developing a novel enantioselective high-performance liquid chromatography-mass spectrometry method, applied to differentiate dextro- and levo-methorphan in post-mortem samples, showcasing its critical role in forensic and clinical toxicology (Jorbenadze et al., 2024).
