一般描述
Chlorophosphonazo III is a highly sensitive reagent and can be used for the spectrophotometric determination of zirconium, titanium, thorium and scandium. 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. Above all that, it has two long wavelength maxima, one at 620 nm and one at 680 nm.
应用
Chlorophosphonazo III was used as a chromogenic agent along with PVC, during the determination of calcium via a disposable optical sensor.

We have characterised the spectroscopic properties of the metallochromic dye dichlorophosphonazo III and describe its use for the determination of changes of Mg2+ concentration in the micromolar range. Using a previously described reconstitution procedure, we incorporated the cGMP-gated channel from

1. Changes in transmission of quasi-monochromatic light were measured in singly dissected, dye-injected twitch fibres following a single propagated action potential. The records, after correction for the intrinsic transmission signal, indicate changes in dye-related absorbance, DeltaA. This paper describes the

This study demonstrates that chlorophosphonazo III (CPZ III) can be used as a contrast agent for photoacoustic calcium imaging. CPZ III can pass across the plasma membrane for labeling intracellular Ca2+ without cytotoxicity. In optical-resolution photoacoustic microscopy (OR-PAM), the photoacoustic
