Pyrogallol Usage

Oxygen Absorbent in Gas Analysis: Due to its extremely strong and rapid oxygen absorption capacity in alkaline aqueous solutions, it is an indispensable special oxygen absorber in chemical laboratories, industrial gas detection, and medical analysis (usually formulated as an alkaline pyrophenol solution) for the quantitative determination and removal of oxygen from mixed gases.
Semiconductor & Photolithography Assistant: In the modern microelectronics industry, it is used as a photoresist stripper, metal circuit cleaning agent, and high-purity reducing agent in semiconductor integrated circuit production.
Photographic Film Developer: Stands as one of the oldest organic black-and-white developing agents in film chemistry. It is highly praised for rendering unique grain structures and sharp highlight contrasts, and is still managed by vintage fine-art printers and industrial radiography labs.
Fine Chemical Intermediate: Used in the synthesis of various antioxidants, dyes (hair dyes), pharmaceutical preparations, and as a polymerization inhibitor in plastics and coatings.
