Quality Control

Our Oxalic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer grades suitable for industrial, technical, and more demanding applications, with quality verified against relevant industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your process requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is 15-25°C.
