Audited Supplier High quality Pyrogallic Acid
Pyrogallol is an organic compound with the formula C6H3(OH)3. It is a white, water-soluble solid although samples are typically brownish because of its sensitivity toward oxygen.It is one of three isomeric benzenetriols.
The ISO certification held by the manufacturer ensures that the production of Pyrogallic Acid follows strict quality management systems and meets international standards for product quality and consistency. This certification guarantees that the manufacturing processes adhere to the guidelines specified by ISO 9001:2015.
Pyrogallic Acid appears as white to light pink crystals and is odorless. It has a molecular weight of 126.11 g/mol. The compound exhibits a melting point of 131-134 °C, although it decomposes at high temperatures.
Pyrogallic acid in chemical analysis field, is gas, flue gas, coking gas, water gas and other gases deoxygenation agent, so nitrogen fertilizer, coking, smelting, petrochemical indispensable deoxygenation analysis reagent.
The acid is soluble in water, alcohol, and ether, allowing for easy incorporation into various formulations and applications. Its high purity level, typically 98% or higher, ensures its effectiveness and reliability in industrial processes.
Pyrogallic Acid finds applications in photography as a developing agent and in the production of dyes and pigments. It is also used as an antioxidant in the rubber industry to prevent oxidation and deterioration of rubber products.
