Quality Control

Our Oxalic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product is tested against rigorous in-house specifications, which typically include assay, identification, and impurity profile analysis. A Certificate of Analysis (COA) is provided with each shipment, detailing the specific results for your quality assurance records. We can support compliance requirements for various industrial and technical grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its nature as a strong acid/organic solvent, ensure containers are kept upright and sealed to prevent moisture absorption and contamination.
