Application
a-furildioxime [(2,2′)-Furildioxime] was used:
- as neutral carrier in Calcium(II)-selective potentiometric sensor, selective electrode used for titration.
- in the synthesis of ketenimines and bis(ketenimines).
- in determination of palladium in water samples by rapid spectrophotometric analysis.
General description
Oximes are selective reagents which react with limited number of metal ions. These form water-insoluble complexes extractable into organic solvents. Furildioxime, a gravimetric and colorimetric reagent for nickel, palladium, platinum and rhenium is prepared by the oximation of furil with hydroxyammonium chloride followed by aqueous recrystallisation using MacKair′s method.

In previous work we found that iron is a factor in skin photodamage, apparently by way of its participation in oxygen radical production. Here we report topical photoprotection with the iron chelator 2-furildioxime (FDO). Our purpose was to determine the
Calcium (II)-selective potentiometric sensor based on a-furildioxime as neutral carrier.
