Description

Oxalic Acid is a versatile and powerful dicarboxylic acid widely utilized across multiple industrial sectors for its chelating, reducing, and cleaning properties. Its effectiveness in binding metal ions and its role as a precursor in chemical synthesis make it a critical raw material for manufacturing and processing. This compound is essential for industries including pharmaceuticals, textiles, metal treatment, and electronics, where precise chemical performance is required. We supply high-purity Oxalic Acid to meet the stringent demands of global B2B customers.

Application

• Metal Cleaning & Surface Treatment: Used as a pickling and polishing agent for ferrous and non-ferrous metals, effectively removing rust and scale.
• Pharmaceutical Synthesis: Serves as a key intermediate and precipitating agent in the production of various active pharmaceutical ingredients (APIs).
• Textile & Leather Processing: Acts as a bleaching agent and mordant in dyeing processes for natural fibers like cotton and wool.
• Industrial Cleaning Formulations: A primary component in specialized cleaners and descalers for boilers, radiators, and cooling systems.
• Chemical Manufacturing: Employed as a reducing agent and as a precursor for oxalate salts, plastics, and other fine chemicals.
• Electronics Industry: Used in circuit board etching and as a component in rare earth element extraction and purification processes.
