Application


  • Triethyl phosphate (TEP) as a green solvent for solid-phase peptide synthesis (SPPS).: This study explores the use of triethyl phosphate as an environmentally friendly solvent for SPPS, highlighting its efficacy in improving peptide synthesis while minimizing environmental impact. The research demonstrates TEP′s potential to replace traditional solvents, thereby promoting greener chemistry practices in peptide production (Nandhini et al., 2024).

  • Utilizing Triethyl Phosphate to Increase the Solubility of Lithium Nitrate for Improved Silicon Anode Performance.: This study focuses on the use of triethyl phosphate to enhance the solubility of lithium nitrate in battery electrolytes, leading to better performance and stability of silicon anodes. The findings suggest significant improvements in battery life and efficiency (Rynearson & Rynearson, 2022).
