Quality Control

Our Oxalic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. The product is tested against rigorous in-house specifications, which may include parameters for assay, heavy metals, chloride, sulfate, and residue on ignition. A comprehensive Certificate of Analysis (COA) documenting purity and conformance is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong bases and oxidizing agents.
