Pyrogallol
Definition:
(n.) A phenol metameric with phloroglucin, obtained by the distillation of gallic acid as a poisonous white crystalline substance having acid properties, and hence called also pyrogallic acid. It is a strong reducer, and is used as a developer in photography and in the production of certain dyes.
Example Sentences:
(1) We adapted the pyrogallol red-molybdate method for total urinary protein to the Cobas Bio centrifugal analyzer.
