Quality Control

Our Oxalic Acid Dihydrate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for industrial and technical applications. A Certificate of Analysis (COA) detailing key parameters such as assay, clarity of solution, and residue on ignition is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption and caking. Recommended storage temperature is between 15°C and 25°C.
