Application


  • Coulometric method with titratable impurity analysis and mass balance method: This study presents a method to convert acidimetric purity to chemical purity for potassium hydrogen phthalate, which is validated using quantitative nuclear magnetic resonance (qNMR) techniques, enhancing the standards for analytical chemistry (Huang T et al., 2023).

  • Triplet states of the nonlinear optical chromophore DCM in single crystals: Investigates the triplet excited states of the nonlinear optical chromophore DCM in potassium hydrogen phthalate single crystals, linking these states to single-molecule dark states, significant for the development of optical materials (Barbon A et al., 2009).
