Chemically known as ethanedioic acid, oxalic acid is the simplest dicarboxylic acid, typically encountered as a white crystalline powder in its dihydrate form (H2C2O4·2H2O). Its physical properties include a density of 1.653 g/cm3 and a melting point of approximately 101.5 °C for the dihydrate. It is significantly stronger than common organic acids like acetic acid, acting as a potent reducing agent and forming stable, water-soluble complexes with metal cations, making it invaluable in numerous processes.

The utility of Oxalic Acid Dihydrate spans across a multitude of sectors due to its strong chemical characteristics. One of its primary applications is in cleaning and bleaching operations. It is particularly effective for rust removal, where it forms a water-soluble ferric iron complex, the ferrioxalate ion, efficiently eliminating iron stains from various surfaces. Beyond rust, it serves as a powerful bleach for materials such as wood, pulpwood, cork, straw, cane, and feathers, restoring their original appearance or preparing them for further processing.

In the textile industry, approximately 25% of produced oxalic acid is utilized as a mordant in dyeing processes, helping dyes bind permanently to fabrics and enhancing color fastness. Its chelating properties are also exploited in specialized applications, including the cleaning of minerals like quartz crystals and pyrite. The electronic and semiconductor industries benefit from its use in electrochemical-mechanical planarization (CMP) of copper layers during device fabrication, ensuring precision and quality in critical components. Other niche uses include its application by some beekeepers as a miticide against parasitic varroa mites.

The industrial production of oxalic acid involves sophisticated chemical processes, primarily through the oxidation of carbohydrates or glucose with nitric acid or air, often in the presence of catalysts. Modern methods also include oxidative carbonylation of alcohols followed by hydrolysis, demonstrating the advanced chemical engineering behind its large-scale availability.
