PHOTOCHEM Pyrogallol CAS 87-66-1 per 500gm (05500-0500PP)
Pyrogallol (chemical formula: C₆H₃(OH)₃) is a white crystalline organic compound belonging to the phenol family. It is also known as 1,2,3-trihydroxybenzene. Pyrogallol is derived from gallic acid and has strong reducing properties. In traditional black-and-white photography, pyrogallol is used as a developing agent. It reduces exposed silver halide crystals in photographic film to metallic silver, forming the image. Pyrogallol-based developers are known for producing high image sharpness and a unique staining effect, which enhances image contrast and detail—particularly useful in large-format and fine art photography. It’s often favored by photographers looking for fine tonal gradation and archival image quality, although it requires careful handling due to its toxicity and sensitivity to air.
