Pyrogallol, also known as 1,2,3-trihydroxybenzene (CAS 87-66-1), boasts a rich history and continues to be relevant in specialized fields, notably in traditional photography and precise chemical analysis. Its chemical properties, particularly its strong reducing ability and its capacity to absorb oxygen, have cemented its place in these applications. NINGBO INNO PHARMCHEM CO.,LTD. provides high-purity Pyrogallol to support these demanding sectors.

Historically, Pyrogallol was one of the earliest and most effective developing agents used in black-and-white photography. Its rapid reduction of silver halide crystals in photographic emulsions formed the basis of image development. While largely superseded by other developers, it remains a niche choice for certain artistic and historical photographic processes, prized for the unique tonal qualities it can impart. Photographers seeking specific effects often look to buy Pyrogallol for its distinct developing characteristics.

In the realm of chemical analysis, Pyrogallol's affinity for oxygen is its defining feature. When dissolved in an alkaline solution, it efficiently absorbs oxygen from gas mixtures. This property is extensively utilized in gas analysis, particularly in determining the oxygen content of air or other gas samples using apparatus like the Orsat apparatus. The rapid color change of the solution from colorless to brown upon oxygen absorption provides a clear indication of its function.
