  99.6% Industrial Oxalic Acid (CAS 144‑62‑7) is a high-purity dicarboxylic organic acid and one of the most essential basic chemical raw materials in modern industrial production. Our export-standard oxalic acid adopts advanced purification and crystallization technology, achieving an ultra-high purity of 99.6% and above. Strict quality control limits moisture content within 0.4%, sulfate below 0.08% and heavy metal residues to an extremely low level, ensuring ultra-low impurities and stable chemical properties. The finished product presents uniform colorless transparent crystals with good fluidity and fast water solubility, completely dissolving in water to form a clear acidic solution without precipitation or floating impurities.

  This high-purity oxalic acid integrates three core industrial advantages: strong acidic corrosion, excellent reducing performance and superior metal complexation capacity. It serves as a professional industrial cleaning and rust removal agent, effectively removing iron oxide, scale and rust stains on metal equipment, pipelines and mechanical surfaces, widely used in machinery rust removal and boiler scale cleaning. In textile and leather industries, it acts as an efficient bleaching agent and pH regulator to remove fabric stains, improve textile whiteness and stabilize leather tanning quality. In chemical and mineral processing fields, it participates in organic synthesis, rare earth extraction and mineral purification, improving processing accuracy and finished product quality.

  Different from low-purity oxalic acid with excessive impurities and unstable activity, our 99.6% high-purity product ensures stable reaction efficiency, less waste residue and lower comprehensive usage cost. It features wide industrial adaptability, stable batch consistency and high safety, fully complying with global industrial chemical export standards. All products undergo strict batch testing and quality inspection to guarantee qualified indicators and reliable application effects. Supported by sufficient inventory reserves and mature global supply chain, we provide long-term stable bulk export supply and cost-effective chemical raw material solutions for global industrial factories, processing enterprises and chemical distributors.
