Quality Control

Our Oxalic Acid is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay, heavy metals, and loss on drying, to meet or exceed standard industry specifications. A Certificate of Analysis (COA) is provided with each shipment, and we can support compliance with various pharmacopeial standards (e.g., USP, BP, EP) upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation. Keep away from strong bases and oxidizing agents.
