Description

Oxalic Acid is a versatile and powerful dicarboxylic acid widely used as a chelating and reducing agent in industrial processes. Its efficacy in metal cleaning, purification, and bleaching makes it a critical raw material for maintaining operational efficiency and product quality. Key industries that rely on this compound include pharmaceuticals, textiles, metal finishing, and water treatment, where it serves as a fundamental processing chemical.

Application

• Metal Cleaning & Surface Treatment: Effective for rust removal, aluminum anodizing, and polishing of rare earth metals.
• Pharmaceutical Synthesis: Used as an intermediate and precipitating agent in the manufacturing of antibiotics and other active pharmaceutical ingredients (APIs).
• Textile & Leather Processing: Acts as a bleaching agent for textiles and a tanning agent in leather production.
• Water Treatment & Purification: Employed as a chelating agent to remove calcium and other metal ions from boiler water and cooling systems.
• Chemical Synthesis: Serves as a reducing agent and a precursor for oxalate salts, perfumes, and dyes.
• Wood & Pulp Bleaching: Used in pulp processing to enhance brightness and remove residual lignin.

Quality Control

Our Oxalic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee supply reliability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
