Pyrogallol, also known as 1,2,3-Trihydroxybenzene, is a white to light brown crystalline solid with the chemical formula C6H6O3. It is used as a reagent in various chemical reactions and processes. Pyrogallol is employed in the production of pharmaceuticals, dyes, and other specialty chemicals. It is also used as a developer in photographic processes and as a reducing agent in certain chemical reactions. Additionally, Pyrogallol finds applications in the formulation of hair dyes and as an antioxidant in certain industrial processes. Its versatility and reactivity make it a valuable chemical in numerous applications. However, Pyrogallol is highly toxic and should be handled with care.
