Benzene123triol

Benzene-1,2,3-triol, also known as pyrogallol or pyrogallic acid, is an organic compound with the chemical formula C6H3(OH)3. It is a white crystalline solid that is soluble in water and alcohol. Pyrogallol is a trihydroxy derivative of benzene, with the hydroxyl groups located at positions 1, 2, and 3 on the benzene ring.

Pyrogallol is a strong reducing agent and readily oxidizes in the presence of air, often turning dark in color. This property makes it useful in various applications. Historically, it was used as a photographic developer and as a hair dye. It has also found use in analytical chemistry for the determination of oxygen, as it absorbs oxygen from gases.

In biological contexts, pyrogallol is found in certain plants and has been studied for its antioxidant and potential medicinal properties. However, it can also be toxic if ingested in significant amounts. Due to its reactivity and potential for oxidation, proper handling and storage are necessary. Its chemical structure and reactivity make it a subject of interest in organic chemistry and related fields.
