orange to brown-red powder | [Uses]
Phenylfluorone is an organic reagent for the spectrophotometric determination of some heavy metals. It 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 Methods]
Recrystallise 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.] |
