Application

  • Cobalt-based MOF Nanoribbons: Tetra-n-butylammonium bromide is utilized in the synthesis of cobalt-based metal-organic framework (MOF) nanoribbons, which are applied for the cycloaddition of carbon dioxide to epoxides. This process is crucial for carbon capture and utilization, demonstrating the compound′s role in green chemistry solutions (Ullah et al., 2022).
  • Phosphate Removal: In environmental applications, Tetra-n-butylammonium bromide is incorporated into polyacrylonitrile composite nanofibers to enhance the removal of phosphate from water, showcasing its utility in water treatment technologies (Wang et al., 2021).
  • Iron(III) Spin-crossover Compounds: This quaternary ammonium salt is used in the synthesis of a rare octacoordinated mononuclear iron(III) compound with spin-crossover properties. This application is significant in materials science, particularly in the development of magnetic materials and sensors (Hao et al., 2020).
  • Protein Extraction Technologies: Its application extends to the enrichment and extraction of hydrophobic proteins using fluoroalcohol-induced coacervates. This technique is vital for biochemical research and the pharmaceutical industry, where efficient isolation and purification of proteins are essential (Koolivand et al., 2018).
