Quality Control

Our Oxalic Acid is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive quality documentation, including Certificates of Analysis (COA) that detail purity, impurity profiles, and physical parameters. Our production adheres to cGMP principles where applicable, and we can support compliance with major pharmacopoeial standards (USP/EP) for specific grades 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). Keep away from heat sources, strong alkalis, and oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent caking.
