Application

  • Enhancement of noncorrosive electrolytes: Research discusses the role of 1-Methylimidazole in improving the properties of noncorrosive electrolytes for battery applications. This study explores how 1-Methylimidazole acts as a high donor number cosolvent, aiding in the release of free anions from commercially available magnesium salts, which could lead to innovations in battery technology (Xiao et al., 2024).
  • Catalytic applications in organic synthesis: 1-Methylimidazole is utilized as a ligand in an air-stable ruthenium(II) complex, facilitating catalytic transfer hydrogenation of ketones from ethanol. This application demonstrates the catalytic versatility of 1-Methylimidazole in synthetic organic chemistry, providing a method for more efficient and sustainable chemical reactions (Beaufils et al., 2024).
  • Functional materials for biomedical applications: Research involving 1-Methylimidazole focuses on developing sodium alginate- and cationic cellulose-functionalized polycaprolactone nanofibers. These materials are designed for specific in vitro and antibacterial applications, indicating the utility of 1-Methylimidazole in the creation of functional biomedical materials (Tolba et al., 2023).
