Quality Control

Our Hypophosphoric Acid is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, impurity profiles, and physical properties. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and properties as a strong acid/organic solvent, the container must be kept tightly sealed to prevent moisture absorption and degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
