Description

Oxalic Acid is a versatile and powerful dicarboxylic acid widely used across numerous industrial processes. Its strong chelating and reducing properties make it an essential chemical for purification, cleaning, and synthesis applications. Key industries that rely on this compound include pharmaceuticals, textiles, metal treatment, and specialty chemical manufacturing, where consistent quality and reliable supply are paramount.

Application

• Metal Cleaning & Surface Treatment: Used as a chelating agent for rust removal, aluminum anodizing, and polishing of rare earth metals.
• 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 for boilers, radiators, and cooling systems due to its calcium-removing capability.
• Chemical Synthesis: Employed as a reducing agent and precursor in the manufacture of fine chemicals, agrochemicals, and dyes.
• Wood Pulp Bleaching: Used in pulp and paper manufacturing to enhance brightness and remove residual manganese.

Quality Control

Our Oxalic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and compliance with international standards. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. A Certificate of Analysis (COA) documenting all test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 strong bases and incompatible materials.
