Because of the tanning effect of catechol on emulsion gelatine, it has many of the properties of pyrogallol, including high acutance and low fog. |
|
Catechol and pyrogallol may be substituted for hydroquinone, but are not as suitable. |
|
The improved pyrogallol method by using terminating agent for superoxide dismutase measurement. |
|
A 1995 report showed that superoxide generated by autoxidation of pyrogallol was quenched by nicotinic acid only at supraphysiologic concentrations. |
|
Pyrogallol, tannic acid, and gallic acid were obtained from Zhunyi Reagents. |
|
Pyrogallol, syringaldehyde and acetosyringone stayed in the still but were mainly lost. |
