Descripción

General description

Chlorophosphonazo III is a highly sensitive reagent and can be used for the spectrophotometric determination of zirconium, titanium, thorium and scandium.[1] It also finds application as an extractant, along with 1-butanol as solvent, for determination of micromolar concentrations of Nd(III), Th(IV) and U(VI) in brine.[2] Above all that, it has two long wavelength maxima, one at 620 nm and one at 680 nm.[3]

Application

Chlorophosphonazo III was used as a chromogenic agent along with PVC, during the determination of calcium via a disposable optical sensor.[4]

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Reagent for the spectrophotometric determination of alkaline earth metals[5]
