What is of  1 2 3Benzenetriol with CAS 87-66-1?
Pyrogallol is a natural oxidant that can generate superoxide (O2) in alkaline solutions through autoxidation to a semiquinone radical. Importantly, the semiquinone radical can react with O2 in an acidic environment to produce a quinone and H2O2. Pyrogallol autoxidation is used in superoxide dismutase activity assays. It can also be used in assays to assess antioxidant capacity. Pyrogallol is used in some biological systems as an O2 scavenger.

Application 

Pyrogallol possesses importance as a spectrophotometric reagent in the determination of niobium and tantalum. The absorptions of niobium and tantalum complexes are usually measured at 340 and 335 nm, respectively. The niobium complex is formed in slightly acidic medium, and the tantalum complex in strongly acidic medium (4 N HC1). The absorption spectra are pH-dependen.
