For any industrial buyer or R&D scientist evaluating chemical intermediates, understanding the precise specifications of a product like Pyrogallic Acid (CAS 87-66-1) is non-negotiable. This white powder, essential for applications ranging from pharmaceuticals to chemical analysis, demands rigorous quality control. As a prominent manufacturer and supplier in China, we emphasize the critical specifications that ensure the optimal performance and reliability of Pyrogallic Acid for your operations.

The primary specification to consider when you aim to buy Pyrogallic Acid is its assay, typically a minimum of 99% or higher. This purity level is crucial for applications such as pharmaceutical intermediates, where even trace impurities can affect the final product's efficacy or safety. Additionally, the physical appearance – an odorless white powder – is a standard indicator of quality. Water solubility, described as 'clear', is another key parameter, indicating the absence of insoluble contaminants.

Further critical specifications include the melting point, which for Pyrogallic Acid generally falls within the range of 131°C-135°C. This property is vital for process control during synthesis. The residue on ignition, usually specified as a low percentage (e.g., 0.025% Max.), indicates minimal inorganic impurities. Similarly, low limits for Chloride (0.002% Max.), Sulphate (0.005% Max.), and Heavy metals (e.g., 5ppm Max. for Lead) are essential, especially for pharmaceutical and food-grade applications.

When sourcing Pyrogallic Acid, it is advisable to inquire about these detailed specifications from potential manufacturers and suppliers, particularly those based in China. Understanding these parameters allows buyers to make informed decisions, compare offerings effectively, and ensure they are purchasing a product that meets their exact industrial requirements. Reliability in supply and adherence to these quality standards are hallmarks of a trusted chemical supplier.
