Chemical. CAS 3682-35-7. Formula C18H12N6. MW BD9837. 2,4,6-Tris2-pyridyl-s-triazine TPTZ is commonly used as a complexing reagent used in spectrophotometric analysis, particularly in the determination of ironII ferrous ions in solution. It forms a blue-colored complex with ferrous ions, which can be quantified using spectrophotometric methods. TPTZ forms a complex with FeII that can be quantified by colorimetric detection at 594 nm as a measure of iron concentration. The formation of this complex is the basis of the ferrous ion assay known as the Ferrozine method. Its sensitivity and specificity for iron make it a valuable tool in analytical laboratories. TPTZ has several other applications. TPTZ can be used as a chemosensor for detecting metal ions. Its ability to form colored complexes with different metal ions can be exploited in developing sensors for metal ion detection in solution.
