TPPS hydrate (=tetraphenylporphyrin tetrasulphonic acid hydrate) ≥95.0% pour détermination spectrophotométrique des métaux de transition, Supelco®
TPPS hydrate (=tetraphenylporphyrin tetrasulphonic acid hydrate)
Reagent for the spectrophotometric determination of ultra trace amounts of transition metals; determination by capillary zone electrophoresis.
4,4′,4′′,4′′′-(Porphine-5,10,15,20-tetrayl)tetrakis(benzenesulfonic acid) [tetrasodium salt hydrate, TPPS] has been used in preparing Co–Al LDH/Fe(III)-TPPS film modified electrode; for demonstrating reversible redox peak attribution to Co(III)/Co(II), with iron(III) porphyrin; making it mediator for electron transfer.
