General description

Duroquinone is an organic oxidant that belongs to the class of 1,4-benzoquinones, is used in redox flow Li–O2 batteries.

Application

  • Role of Duroquinone in Photosynthetic Research: A study on purple bacterial photosynthetic reaction centers highlighted Duroquinone′s role when incorporated into the QA binding site, impacting the isotope edited FTIR difference spectra, crucial for understanding energy conversion processes in photosynthesis (Zhao et al., 2013).
  • Duroquinone as a Molecular Ion Source: Research demonstrated the generation of molecular negative ions by Duroquinone, showcasing its potential in mass spectrometry applications for studying molecular ionization and longevity (Khvostenko et al., 2012).
  • Duroquinone in Biochemical Sensors: Investigation into the optimization of gold electrode surfaces with photosystem II monolayers revealed Duroquinone′s critical role in enhancing sensor responses, applicable in biochemical sensor technology (Maly et al., 2005).
  • Cytotoxicity of Duroquinone Congeners: A comparative study of 14 p-benzoquinone congeners, including Duroquinone, used quantitative structure-toxicity relationships to evaluate cytotoxicity in rat hepatocytes and PC12 cells, relevant for safety assessments in chemical manufacturing (Siraki et al., 2004).
