Phenylfluorone Usage And Synthesis
  • Chemical Propertiesorange to brown-red powder
  • Uses9-Phenyl-2,3,7-trihydroxy-6-fluorone is used in presence of cetylpyridinium chloride for spectrophotometric determination of copper(II) in blood serum. It is used in the determination of germanium. It is also used to determine molybdenum(VI).
  • Purification MethodsRecrystallise it from warm, acidified EtOH by addition of ammonia. The crude material (1g) can be extracted with EtOH (50mL) in a Soxhlet apparatus for 10hours to remove impurities. Impurities can be detected by paper electrophoresis. The triacetate forms yellow needles from EtOH (m 230-233o). [Petrova et al. Anal Lett 5 695 1972, Beilstein 18 H 199, 18 I 404, 18 III/IV 2824.]
