Quality Control

Our Oxalic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including technical and purified, tailored to specific industrial needs. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles. Our quality commitment ensures the product meets the relevant standards for its intended application.

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). This product is hygroscopic (moisture-sensitive) and a strong acid; ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and stored separately from incompatible materials such as strong bases and oxidizers.
