At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing the highest quality chemical raw materials to support a vast array of industries. Among our premier products is Pyrogallol, also known as pyrogallic acid or 1,2,3-trihydroxybenzene. This organic compound, with the chemical formula C6H6O3, is a cornerstone material recognized for its exceptional purity and versatility. Supplied as a white, glossy crystalline powder, our Pyrogallol meets stringent international standards, making it a reliable choice for applications demanding superior performance and consistency.

Unpacking the Properties and Grades of Pyrogallol
Pyrogallol is a benzenetriol that is highly valued for its reactivity and physical properties. It is readily soluble in water, ethanol, and ether, which facilitates its use in various formulations and chemical processes. A key characteristic of Pyrogallol is its powerful reducing ability and its sensitivity to oxygen, especially in alkaline solutions, a property that is harnessed in many analytical and industrial applications. However, this also means it requires careful handling and storage; it should be kept in a cool, dry, and well-ventilated location to prevent degradation from air and light, which can cause the white powder to darken over time.

To cater to the specific needs of different industries, we offer Pyrogallol in several grades, each with guaranteed specifications:
- Analytical Reagent (AR Grade): With a purity of ≥99.8%, this is the highest grade available. It is designed for sensitive laboratory applications, including the analysis and determination of trace metals like antimony, bismuth, cerium, iron, and molybdenum. Its specifications meet rigorous standards, ensuring minimal interference and maximum accuracy in analytical testing.
- Chemically Pure (CP Grade): This grade has a purity of ≥99.5% and is suitable for a wide range of applications in fine chemical synthesis and pharmaceutical intermediate production where high purity is essential.
- Industrial (IND) Grade): With a purity of ≥99.0%, this grade is a cost-effective solution for large-scale industrial processes such as textile dyeing, manufacturing of photosensitive materials, and certain chemical preparations.

A Spectrum of Industrial Applications
The unique chemical structure of Pyrogallol makes it an indispensable component in numerous sectors. Its utility is broad and continues to expand as new technologies emerge.

Pharmaceuticals and Fine Chemicals: Pyrogallol serves as a critical starting material or intermediate in the synthesis of various pharmaceutical compounds. Its antioxidant properties are of particular interest. It is a precursor for several drugs, including those aimed at treating neurodegenerative and cardiovascular diseases. In the realm of fine chemicals, it is used to produce specialized molecules and antioxidants for various end-products.

Dyeing and Photography: The compound has a long history of use in the dyeing industry, particularly for hair, furs, and leather, where it imparts rich, lasting colors. In the world of photography, Pyrogallol was one of the earliest developing agents for black-and-white film. Though less common now, it is still favored by some photographers for the unique tonality and staining effect it produces, which can enhance the archival stability and visual character of prints.

Analytical Chemistry and Gas Analysis: One of the most classic applications of Pyrogallol is in gas analysis. An alkaline solution of Pyrogallol rapidly and quantitatively absorbs oxygen from a gas mixture. This reaction is widely used in Orsat analyzers and other laboratory setups to determine the oxygen content in air or other gas streams. This makes it an invaluable reagent for environmental monitoring and industrial process control.

Microelectronics and Plating: In the high-tech microelectronics industry, Pyrogallol is used in specialized formulations for cleaning and etching processes. Its reducing properties are also harnessed in color printing plate making and for the analysis and deposition of rare metals, ensuring precision and high performance in these demanding applications.

Food Preservation and Other Uses: The antioxidant capabilities of Pyrogallol have also been explored for food preservation, where it can inhibit spoilage caused by oxidation. Furthermore, it is used in producing new photosensitive materials and as a component in light industry daily chemicals.
